Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, gave the instructions after the bridge, located in Zhashui County in Shangluo City, collapsed at approximately 8:40 p.m. on Friday due to flash floods caused by heavy rain. Twelve people were killed while 31 others remained missing as of 12 p.m. on Saturday.

The immediate priority is to carry out rescue operations, make every effort to search for the missing and minimize casualties, Xi said, also urging efforts to assist the families of those affected.
