The number of known cases of women and girls trafficked from Vietnam to China more than doubled last year, China’s official Xinhua news agency has said.
Xinhua said 125 cases were detected of Vietnamese trafficked into China’s Guangxi province, across the border.
This is partly due to better detection by both governments, but trafficking overall is also thought to be rising.
Analysts warn that China could replace Thailand in the next few years as the region’s trafficking hub.
