Tropical Storm Maysak caused deadly flooding in parts of northern and southern China after making landfall in Vietnam and moving north into Guangxi and Liaoning provinces on July 4–5, 2026. Heavy rains associated with the storm led to five fatalities in northern China.

On Saturday evening, two villagers died in a mountain flash flood in the eastern part of China's Inner Mongolia region. One person drowned while herding cattle, and another fell into water while driving a cattle herd away. Additionally, three individuals died on Saturday in Fushun city in Liaoning province, located approximately 390 kilometers (240 miles) southeast of the Inner Mongolia region.

Fushun experienced a heavy rainstorm for several hours early Saturday, with rainfall in one area reaching up to 32.9 centimeters (13 inches). About 3,600 residents were relocated to safer areas due to the conditions. After the winds subsided, crews in Mong Cai used chainsaws and heavy machinery to clear debris and reopen roads.

Tropical Storm Maysak initially made landfall in Vietnam's Quang Ninh province on Saturday night, with winds recorded at 101 kilometers (63 miles) per hour. The storm then headed north into China's Guangxi region on Sunday, weakening from a severe tropical storm to tropical storm strength as it moved inland. In Fangchenggang city, Guangxi, rivers overflowed, submerging cars up to their roofs. Rescuers used inflatable boats to reach people who were trapped. Residents described the flooding in Fangchenggang as the most severe in two decades. Tropical Storm Maysak also uprooted trees in Dongxing, a city bordering Vietnam.
