A North Korean cargo train has reportedly pulled into a Chinese border town in what would be the first confirmed crossing since its anti-coronavirus border lockdowns began. North Korea has not officially reported any Covid-19 cases and has imposed strict anti-virus measures, including border closures and domestic travel curbs since the pandemic began in early 2020. A North Korean freight train crossed the Yalu River railway bridge to arrive in the Chinese town of Dandong on Sunday, the South Korean news agency Yonhap said, citing multiple unnamed sources.
