Pentagon's decision of disinviting Chinese military from the 2018 Rim of the Pacific Exercise is a decision that was taken lightly and was unhelpful, visiting Chinese State Councilor and Foreign Minister Wang Yi said in Washington on Wednesday.

Pentagon on Wednesday disinvited China from a major US-hosted naval drill, the Rim of the Pacific exercise, known as RIMPAC, which is held every two years in Hawaii in June and July.

"We find that a very unconstructive move; it's also a decision that's taken lightly," Wang told reporters in Washington after meeting with US Secretary of State Mike Pompeo.
