For the first time in nearly four years new staff have been allowed at the Russian embassy in the North Korean capital of Pyongyang, the delegation said on Thursday, after anti-pandemic measures blocked most travel and lead many embassies to close. Russia would be only the second embassy known to be allowed new staff, after China's new ambassador entered in March. The arrival of the new Russia staff comes amid U.S. officials' suggestions that North Korean leader Kim Jong Un may visit Russia soon to see President Vladimir Putin, possibly to discuss arms deals.
