China to Return US Underwater Drone

China has agreed to return a US underwater drone, seized by a Chinese naval vessel in the South China Sea. Beijing earlier told the United States to stop maritime surveillance operations in the seas off China. The Pentagon said the drone was being used to carry out scientific research, while US President-elect Donald Trump accused the Chinese of "stealing".
