The U.S. is deploying two unmanned surveillance planes to Japan to monitor military activities in China and North Korea.
Japan's Asahi Shimbun reported Saturday that the first Global Hawk drone arrived at Misawa (MEE-SA-WA) Air Base base early Saturday, local time, and the second one will arrive on Wednesday.
The two drones will fly missions over the South and East China Seas, and over the Korean peninsula twice a week through October.
It marks the first time the U.S. has deployed unmanned spy drones to Japan.
Meanwhile, Chinese state media has criticized the U.S., South Korea and Japan for intensifying their military surveillance in the area where China is holding joint naval drills with Russia.
It says all three countries have deployed patrol planes to monitor the drills, which will officially end next Monday.
