BEIJING -- President Xi Jinping has urged all-out search and rescue efforts, and flood control and disaster relief work after mountain torrents since Thursday in Northwest China's Gansu province have left 10 people dead and 33 missing as of 3:30 pm Friday.

Xi, also general secretary of the Communist Party of China Central Committee and chairman of the Central Military Commission, attached great importance to the situation of the disaster triggered by continuous heavy rainfall, which hit areas including Yuzhong county of Lanzhou, the provincial capital.

The immediate task is to search and rescue the missing people by every possible means, relocate and resettle residents in danger, minimize casualties, and restore communication and transportation as soon as possible, Xi instructed.

He noted that given the recent frequent occurrence of extreme weather, local authorities and relevant departments must strengthen risk forecasting and early warning, identify and rectify hidden hazards, reinforce emergency response and on-call duty arrangements, and enhance flood control and disaster relief work with targeted measures so as to ensure people's safety during the flood season.
