Taiwan's Defense Ministry said Tuesday it is watching the movements of a Chinese aircraft carrier and assessing China's military activities as security sources said Beijing could launch new war games as soon as this weekend.

China, which claims democratically governed Taiwan as its own territory, has held two rounds of war games around the island so far this year, and its forces operate nearby on a daily basis.

China has a strong dislike of Taiwan President Lai Ching-te, whom it calls a "separatist," and sources have said it could launch new drills to coincide with his trip to the Pacific this week that includes visits to Hawaii and Guam.
