Ren criticized the U.S. decision as "not constructive" and called on Washington to "focus on the overall situation, abandon the zero-sum mentality, properly handle differences, and try to make the mil-to-mil relationship a stable factor for China-U.S. relations".
The supply ship Gaoyouhu and the hospital ship Peace Ark are gonging to set sail to Hawaii to join 2016 Pacific Rim (RIMPAC) on June 15, 2016 in Zhoushan, Zhejiang Province of China. In 2014 - the PLAN's first RIMPAC - China sent a Type 815 auxiliary general intelligence surveillance ship to spy on the exercise.

Brunei, Malaysia, the Philippines, Taiwan and Vietnam also have claims in the sea.
The Pentagon also cited its objections to China's recent landing of bomber aircraft at Woody Island. China has generally participated.
But the United States now says China's behaviour in the South China Sea runs counter to the spirit of the drills.
