HANOI -- China has tightened its land border with Vietnam amid worries over the omicron variant of COVID-19, dealing a blow to trade from the Southeast Asian country as it battles to get its economy back on track in the face of the pandemic.
Beijing informed Vietnam on Thursday that foreign drivers would be barred from crossing the border between the two countries from Friday due to a request from Chinese health authorities, with similar measures also affecting China's borders with Myanmar and Laos. China is Vietnam's second-largest export market and its biggest source of imports.
