Amid the Chinese assertion in the South China sea and stationing of its military assets during recent past, the Pentagon appears to be miffed.
So much so that the US defence department Pentagon went ahead and disinvited China from participating in a major naval exercise.
Lt. Col. Christopher Logan, a Pentagon spokesman, said the Defense Department had withdrawn an earlier invitation to the Chinese navy to participate in the Rim of the Pacific (RIMPAC) drill.
The drill is a biennial naval exercise that involves more than two dozen nations.
It need be recalled that China has only recently placed anti-ship missiles, surface-to-air missiles and electronic jammers on the Spratly Islands in the South China sea.
The islands are however claimed even by several other countries including Malaysia, Vietnam and the Philippines.
The Pentagon said that China has also landed bomber aircraft at Woody Island, which is another disputed area to the north claimed by China and Vietnam.
The decision to exclude China from the exercise is likely to intensify tensions with a country the Pentagon has identified, along with Russia, as a chief rival to American military power and a focus of planning.
The Chinese government had not issued a public response to the decision.>
