Beijing urges global effort to back peace bid

Given that countries around the world have become a shared community that is indivisible, Wang said unlimited sanctions would damage the stability of the international supply chains, intensify food and energy crises and harm the livelihoods of people amid a sluggish global economic recovery.

With the conflict now in its third week, attention has been focused on the plight of civilians at risk.

At least 35,000 civilians were evacuated from besieged Ukrainian cities on Wednesday, Ukrainian President Volodymyr Zelensky said.

In a video address late on Wednesday, the Ukrainian leader said three humanitarian corridors had allowed residents to leave the cities of Sumy, Enerhodar and areas around the capital Kyiv.

The evacuations came after Moscow and Kyiv agreed on Wednesday to open more corridors, offering a glimmer of hope for terrified civilians trapped in bombarded cities.

More than 5,000 people were evacuated a day earlier from Sumy, a city near the Russian border and that has been the scene of heavy fighting.

The International Organization for Migration, the United Nations' migration agency, said more than 2.3 million people had fled Ukraine by Thursday.

In another consequence of the conflict, Ukraine's nuclear regulator Ukrenergo said on Wednesday that power had been cut to the Chernobyl nuclear plant, but the International Atomic Energy Agency claimed there was "no critical impact on safety".

The news from the site of the world's worst nuclear disaster came as the IAEA said data transmission was also lost at the Zaporizhzhia atomic plant, Europe's largest.
