Four people were killed by falling trees, one died when a building collapsed and one was drowned in Guangxi Zhuang Autonomous Region, Xinhua reported citing the regional civil affairs department.

In Hainan Province, one person died and another was missing after the storm brought strong winds and rainstorms to the island, said Chen Wu, deputy head of the provincial flood control headquarters, Wednesday.

Kalmaegi has affected more than 2.8 million people and caused 5.78 billion yuan ($940 million) in direct economic losses in agriculture, fisheries, road and water facilities in Hainan, said the official.
