But Mr Putin said the plan could be put forward only "when they are ready for it in the West and in Kyiv".

The Russian leader met Chinese President Xi Jinping on Tuesday in Moscow to discuss the conflict, and relations between the two countries.

China's plan, published last month, does not explicitly call for Russia to leave Ukraine.

Listing 12 points, it calls for peace talks and respect for national sovereignty, without specific proposals.

The video-sharing app, owned by Chinese company ByteDance, is accused of posing a national security risk through data gathered from millions of users.

A request for a change in ownership, first reported in the Wall Street Journal (WSJ), was confirmed to BBC News by TikTok.

The company said a forced sale would not change its data flows or access.

The White House has not yet responded to a BBC News request for comment.

For years American officials have raised concerns that data from the popular app could fall into the hands of the Chinese government.

It comes after the US on 4 February shot down a suspected spy balloon over its airspace - which China said was one of its weather balloons gone astray.

Relations between the two countries have since deteriorated. In recent days, the US has also shot down a number of other unidentified objects.

Questioned on Monday, Beijing said the US had made many airspace breaches.

"It's not uncommon as well for the US to illegally enter the airspace of other countries," said foreign ministry spokesman Wang Wenbin at a regular press briefing.

The Department of Defence confirmed its fighter jets brought down the balloon over US territorial waters.

BBC reports China's foreign ministry later expressed "strong dissatisfaction and protest against the US's use of force to attack civilian unmanned aircraft".

Footage on US TV networks showed the balloon falling to the sea after a small explosion.

An F-22 jet fighter engaged the high-altitude balloon with one missile - an AIM-9X Sidewinder - and it went down about six nautical miles off the US coast at 14:39 EST, a defence official told reporters.

We watched the skilled craftsmen as they carved elaborate decorations into the freshly-cut wood. Over recent months, they say, they haven't had time to stop.

One villager, a customer, said that at times the coffins have sold out. Laughing with a dose of the black humour you find in the area, he added that those in the funeral industry had been "earning a small fortune".

BBC reports there has been much debate about the real number of Covid-19 deaths in China, after the virus ripped through its megacities.

While her father was never tested, Ailia and her mother were both confirmed positive around the same time and she believes Covid-19 was a cause in his death.

As hundreds of millions of Chinese travel to reunite with families for the Lunar New Year holiday starting 21 January, many will do so after mourning relatives who died in the Covid-19 wave that has raged across the world's largest population.

A computational biologist says Covid-19 deaths in China may actually be up to ten times higher than reported.

University of Auckland Professor David Welch said given the country's population of 1.4 billion people, he expects cases and deaths are likely much higher.

"Looking at comparable countries, maybe Hong Kong or Japan, we'd expect hundreds of millions of cases in China by now.

"Assuming that say 1 in 1000 people who gets Covid - that's a very conservative estimate - dies, that adds up to hundreds of thousands of deaths."

The removal of most restrictions last month has led to a surge in cases.

But China has stopped publishing daily cases data, and has announced only 22 Covid deaths since December, using its own strict criteria.

"We believe that definition [of a Covid death] is too narrow," WHO emergencies director Dr Michael Ryan said.

Dr Ryan said China's figures "under-represent the true impact of the disease in terms of hospital admissions, in terms of ICU admissions, and particularly in terms of deaths".

The US, India and the UK are among the nations that have introduced mandatory testing for arrivals from China.

BBC report the country has recently seen a surge in Covid cases following the easing of its strict controls.

And there are fears that cases and deaths are being vastly underreported.

China's last daily Covid update, on 24 December, reported fewer than 5,000 cases - but some analysts claim the daily caseload is already over two million, and could peak at almost four million this month.

The pileup took place on a bridge that was shrouded in heavy morning fog, which caused multiple vehicles to crash, according to state-owned The Global Times.

Photos from the scene show the long multi-lane bridge, stretching across fields and the Yellow River, strewn with vehicles crammed into each other. Cars, cargo trucks, lorries and other vehicles can be seen in the pileup.

CNN reports in videos filmed from the ground, the air is still thick with fog. One clip shows a truck sliding forward, crashing into several smaller cars, as sirens ring in the distance.
