BEIJING (AP) — Heavy rains have left five people dead in northern China while a tropical storm toppled trees and submerged cars in the nation's south, state media reported Sunday.

Two villagers died in a mountain flash flood Saturday evening in the eastern part of China's Inner Mongolia region, the official Xinhua News Agency said. One drowned while herding cattle and the other fell into water while driving a cattle herd away, the report said.

Three other people died the same day in neighboring Liaoning province's Fushun city, about 390 kilometers (240 miles) to the southeast, Xinhua said. It did not provide details on how they died.

A heavy rainstorm battered Fushun for several hours early Saturday with rainfall of up to 32.9 centimeters (13 inches) in one area, according to state media reports. Video posted online showed streets turned into lakes. About 3,600 residents were relocated to safer areas.

In southern China, Tropical Storm Maysak headed north into the Guangxi region on Sunday after making landfall the previous night with winds of 101 kilometers (63 miles) per hour in neighboring Vietnam's Quang Ninh province. It weakened from severe tropical storm to tropical storm strength as it moved inland.

Rivers overflowed in Guangxi's Fangchenggang city, submerging cars up to their roofs, footage on state broadcaster CCTV showed. Rescuers used inflatable boats to reach trapped people. Residents described it as the most severe flooding in two decades, according to a China News Service report.

In Vietnam, the storm knocked down trees and ripped metal roofs off buildings in the town of Mong Cai on Saturday evening, Vietnamese state media said. Crews used chainsaws and heavy machinery to clear debris and reopen roads after the winds subsided.

Maysak also uprooted trees in Dongxing, a city that borders Vietnam. The tropical storm dumped rain on China's Hainan island last week before crossing water and making landfall again in Vietnam.
