is russia subject to the same limitations as china is in this exercice? other nations also?In 2014, for the first time in history, the People's Republic of China has been invited to participate in the exercises, though because of sensitive defense related issues and associated legal restrictions, the PRC role will be limited to less sensitive exercises, like disaster relief.
US law prohibits the U.S. military from any military exercises with the PRC if it could possibly, “create a national security risk due to an inappropriate exposure” to technology, sensores, armaments, control, etc., including joint combat operations.
However, there is an exemption for operations or exercises related to search-and-rescue and humanitarian relief. The Chinese People's Liberation Army Navy (PLAN) participated with the US Navy in 2012 in a counterpiracy drill.
Lieutenant Colonel Catherine Wilkinson, a Pentagon spokeswoman, said China’s participation in RIMPAC would adhere to US law and said that precautions had been taken by the Navy in drills to avoid revealing sensitive information.
“The US Navy has operational security safeguards to protect US technology and tactics, techniques and procedures from disclosure,” Wilkinson said.
