“Beijing is pushing out in all directions, from the South China Sea to several Japanese islands, with an eye on the eastern Pacific that laps American shores.
On the day after Christmas, three Chinese boats, one modified to carry four cannons, entered Japan’s territorial waters surrounding the Senkaku Islands in the southern portion of the East China Sea. The move, a dangerous escalation, is the first time the People’s Republic of China sent an armed vessel into an area that Tokyo claims as its own.
The sending of the three Chinese vessels on Dec. 26 appears to signal a new phase of incursions to grab not just the Senkaku Islands but the nearby—and far more important—Ryukyu Islands. Those include Okinawa, which hosts more than half of the 54,000 American military personnel in Japan, including those at Kadena Air Force Base, the Army’s Fort Buckner and Torii Station, eight Marine Corps camps, as well as Air Station Futenma and Yontan Airfield, and the Navy’s Fleet Activities Okinawa.”
