By Nguyen Phuong Linh and Matt Spetalnick HANOI/WASHINGTON (Reuters) - Anti-China violence subsided in Vietnam on Friday after the prime minister called for calm, but the United States said China's "provocative" actions in maritime disputes were dangerous and had to stop. Thousands of people attacked businesses and factories in Vietnam's industrial parks earlier in the week, targeting Chinese workers and Chinese-owned businesses after Beijing parked an oil rig in a part of the South China Sea claimed by Hanoi. The riots risk derailing a major driver of the country's economic growth - industrial parks account for more than 30 percent of Vietnam's exports and have attracted around $110 billion in foreign direct investment.
Boats sailed through the streets of a Serbian town on Friday on a mission to rescue people trapped by rising waters as the worst floods ever recorded swept Serbia and Bosnia. Some residents of Obrenovac, 30 km (20 miles) southwest of the capital Belgrade, were stranded on the roofs of their homes, calling for help. Thousands have been evacuated from homes in central and western areas of Serbia. Another 65,000 were without electricity in neighboring Bosnia.
