Omicron variant may change course of COVID******Xinhua。

Certain features of the Omicron variant, including its global spread and large number of mutations, suggest it could have a major impact on the course of the COVID-19 pandemic, said the chief of the World Health Organization on Wednesday.。

With the Omicron variant now present in 57 countries, WHO Director-General Tedros Adhanom Ghebreyesus warned at a press briefing that it can spread more rapidly than previous variants.。

"We are now starting to see a consistent picture of rapid increase in transmission (rates), although for now the exact rate of increase relative to other variants remains difficult to quantify," he said.。

"Emerging data from South Africa suggest increased risk of re-infection with Omicron, but more data are needed to draw firmer conclusions," he added.。

While some evidence might suggest that Omicron causes milder symptoms than the earlier Delta variant, it's still early days to draw any final conclusions, WHO experts have said.。

According to Mike Ryan, executive director of the WHO's Health Emergencies Program, although the evolutionary nature of the virus makes it more transmissible as it mutates, this doesn't necessarily make the virus less severe, as has been suggested by some "urban legends."

Whether or not a mutation turns out to be milder or more lethal is a matter of chance, he said.。

As studies of the latest COVID-19 variant are evolving, the WHO says it still needs days or even weeks for global epidemiological data to come in, be analyzed and then to draw any firm conclusions.。

It's also still premature to say that Omicron could result in a significant reduction in vaccine effectiveness, according to WHO Chief Scientist Soumya Swaminathan.。

The WHO has called on all countries to increase surveillance, testing and sequencing, and to submit more data to the WHO Clinical Data Platform using an updated online case reporting form.。

China calls for calm as Russian move escalates Ukraine crisis******

The Chinese Foreign Ministry on Tuesday called on all parties in the Ukraine issue to remain calm, ease tensions and resolve differences through dialogue and negotiations.

Foreign Ministry spokesperson Wang Wenbin made the remarks at a daily press briefing in Beijing.

State Councilor and Foreign Minister Wang Yi had a telephone conversation with United States Secretary of State Antony Blinken earlier in the day, expounding China's stance on the Ukraine crisis.

"China is concerned about the evolving situation in Ukraine, and China's position on the Ukraine issue is consistent," the spokesperson quoted the foreign minister as saying, noting that the legitimate security concerns of any country should be respected, and the purposes and principles of the United Nations Charter should be upheld.

He said the current situation in Ukraine is closely related to the delay in the effective implementation of the new Minsk Agreements, and China will continue to make contacts with all relevant parties according to the merits of the matter itself.

China once again calls on all parties to exercise restraint, realize the importance of implementing the "indivisibility of security" principle, ease tensions and resolve differences through dialogue and negotiations as the situation in Ukraine is getting worse, the spokesperson said.

Russian President Vladimir Putin on Monday signed two decrees recognizing "the Lugansk People's Republic" and "the Donetsk People's Republic" as independent and sovereign states.

"I consider it necessary to make a long overdue decision – to immediately recognize the independence and sovereignty of the DPR and the LPR," Putin said in a televised address to the nation.

The crisis of European security occurred due to the eastward expansion of the North Atlantic Treaty Organization, which has led to the loss of mutual trust with Russia, Putin stressed.

He called it just "a matter of time" for NATO to accept Ukraine as a member state and then build facilities on its territory so that the level of military threats to Russia will rise dramatically.

As Moscow asked the US and NATO for security guarantees, the Western countries precisely ignored Russia's fundamental concerns and nothing has changed in their position, Putin noted.

In such a condition, Russia "has every right to take retaliatory measures to ensure its own security," the president said.

Russia's move caused a diplomatic and economic backlash on Tuesday after Putin ordered his forces into Ukraine to secure the two regions.

Germany announced that it was halting certification of the Nord Stream 2 gas pipeline from Russia and said the European Union would adopt "robust and massive" economic sanctions.

Britain slapped sanctions on five Russian banks and three billionaires, in what Prime Minister Boris Johnson called "the first barrage" of measures in response to the Kremlin's actions in Ukraine.

The five banks targeted – Rossiya, IS Bank, General Bank, Promsvyazbank and the Black Sea Bank – and three people sanctioned will see any UK assets frozen.

The individuals concerned – Gennady Timchenko, Boris Rotenberg and Igor Rotenberg – will be banned from traveling to Britain and all United Kingdom individuals and entities will be banned from dealing with them and the banks.

The US will also impose sanctions on Moscow, a White House spokesperson said on Tuesday without giving details.

UN Secretary-General Antonio Guterres on Monday expressed deep concern over Russia's move on Donetsk and Lugansk.

The UN chief called for "peaceful settlement" of the conflict in eastern Ukraine, in accordance with the Minsk Agreements.

"The secretary-general considers the decision of the Russian Federation to be a violation of the territorial integrity and sovereignty of Ukraine and inconsistent with the principles of the Charter of the United Nations," said the statement.

China's permanent representative to the UN, Zhang Jun, on Monday called on all parties to seek "reasonable solutions."

"We welcome and encourage every effort for a diplomatic solution, and call on all parties concerned to continue dialogue and consultation, and seek reasonable solutions to address each other's concerns on the basis of equality and mutual respect," Zhang told the Security Council emergency meeting, called at the request of Kiev, the US, five European nations and Mexico.

"China has been paying close attention to the latest development of the situation in Ukraine. We have fully elaborated on our position at the previous two meetings of the Security Council," Zhang said.

Feature: Bringing skiing to more children at South Africa's only commercial ski resort******

by Sportswriter Lyu Tianran

CAPE TOWN, Dec. 21 (Xinhua) -- With a number of snowy mountains in winter, South Africa has one of a few known public ski resorts in Sub-Saharan Africa, although man-made snow has to be used together with natural snow.

The history of skiing in the southernmost country on the African continent dates to 1929 when members of The Mountain Club of South Africa started skiing in the mountain range in the western region. It was in 1994 that the country has its first and only commercial ski resort, Tiffindell, according to Snow Sports South Africa, officially recognized sports body for alpine skiing, snowboarding, freestyle skiing, Nordic Combined and bobsleigh and skeleton.

There is "surprisingly" a lot of people in South Africa like skiing, yet it is still a small sport, with major sports like rugby taking more focus, said Alexander Heath, better known as Alex Heath, the three-time Winter Olympian and the only coach of the South African national skiing team.

He coaches two development programs in Tiffindell for children who like skiing and future skiers who can compete at the international level.

"I still believe we (skiing) have a place in the sporting community here. and I think we are doing amazing things," said Heath, adding that skiing can teach children "amazing values in life" and opens doors for them to go overseas when the opportunity is limited in other things they do.

Tiffindell started the Ikhephu Ski Pups Junior Development Club in 1996, to give local children who live in the area an opportunity to ski, and also develop the children who might work in the sector in the future, as there were no other formal sports opportunities for the youth in that area, according to Christina Olivier, chairperson of Ikhephu.

Later in 2014, the Winter Sports Academy ran by Heath was established here to improve the level of children who ski so that they can compete at the international level.

Heath, who started skiing in England at the age of nine, opted to coach children in Tiffindell after he stopped racing in 2006 as he thought it was an opportunity to help kids enjoy this "amazing" sport in South Africa.

Located at an elevation of 2720 meters on the slope of a 3001-meter mountain in southeastern inland near Lesotho, Tiffindell Ski Resort has an international-level ski area that offers three months of skiing each year from June to August in winter, with natural and man-made snow, and had been hosting ten International Ski Federation (FIS) races every year that attract skiers from all over the world, until the outbreak of COVID-19 pandemic in 2020.

At Ikhephu, meaning "snow" in South Africa's Xhosa language, where members mainly ski for the interest, the youngest child could be as little as three years old, and one can keep his membership until 21. While the youngest skier at the academy is about nine, and the skiers are mostly school children.

During the winter season, over 60 children would first learn how to ski at the development club, and then go to bigger slopes and be given instructions in skiing. Around 20 identified athletes at the academy will stay on the mountain for almost the entire season, and they will do ski training in the morning on the slopes for three hours or so, and then do schooling at the resort in the afternoon.

The two programs get support from the national Department of Sports, Arts and Culture, which covers some fees for children.

Over years, four athletes from the Winter Sports Academy qualified for Winter Youth Olympic Games and one qualified for Olympic Winter Games. According to Heath, almost all the athletes of the national ski team came out from the academy.

Unfortunately, due to COVID-19 that led to the temporary closure of Tiffidal in the past two winters and related travel restrictions, none of the South African skiers have qualified for the next Winter Olympics to be held in Beijing next February, although one skier who is training in Europe is still attempting to qualify.

"We were hoping to qualify for Beijing, but unfortunately it wasn't possible," said Heath. "I'm very sad that we wouldn't be in Beijing because we have some athletes that would have had the chance."

"Going forward, I'm pretty confident that we would be able to qualify athletes, men and women, for future Olympic Games," he said.

As Tiffindell opened when countries in the northern hemisphere were in summer, it attracted a lot of interest from overseas like South Korea, Israel, Italy, UK, Sweden, France and Morocco, especially for aspirants who sought for qualifying by making points at the competitions, according to Olivier, who organized these international competitions. She believed that skiers will return as long as the ski resort reopens.

While expecting the reopening of Tiffindell, she said the development programs plan to reach more children in the country.

"We are planning to involve children from wider areas in South Africa. We focus on local communities mostly, but if the resort reopens, we have plans to involve children from all over the country to join in our ski camps," said Olivier. Enditem
