HANOI—Nationwide protests over new economic zones for foreigners have spiraled into chaos in the central Vietnamese province of Binh Thuan, where anti-Chinese sentiment boiled over as people hurled bricks and Molotov cocktails at police.
The protests, by thousands of people in several cities, were fueled by concerns that a draft legislation to develop economic zones offering land leases of up to 99 years would be dominated by investors from China, a neighbor with which Vietnam has a rocky history.
