BEIJING, May 18 -- China's State Flood Control and Drought Relief Headquarters activated Level-IV emergency response measures in readiness for possible flooding in Fujian and Guangxi on Sunday.

A work team has been dispatched to Guangxi Zhuang Autonomous Region, south China, to assist and provide on-site guidance, according to the Ministry of Emergency Management.

Heavy rainstorms are forecast to sweep parts of Guangxi, Guangdong, Fujian and Zhejiang from Sunday to Monday, according to the weather forecast.

Authorities have urged efforts to closely monitor both rainfall and flood developments, strengthen meteorological early warnings and emergency response, and relocate people in dangerous areas to ensure their safety.

China has a four-tier flood-control emergency response system, with Level I being the highest level.
