China Threatens to Bomb North Korean Nuclear Facilities if North Korea "Crosses Chinese Bottom-Line", and moves troops to North Korean border.
Chinese diplomacy does Judo with American demands, tells North Korea, "We are not acquiescing to an American attack. This is our business and the PLA will attack if you cause problems."
China clearly defines sphere of influence, while calling for denuclearized Korean Peninsula.
As tensions over North Korea's nuclear program mount, the United States Air Force has deployed a WC-135 (a.k.a. the "Nuclear Sniffer"), an aircraft that specializes in detecting radioactive debris after the detonation of a nuclear device, to Okinawa, Japan to assist with monitoring for potential nuclear tests in the region.
Donald Trump called President Xi on the phone to discuss trade and the developing North Korean situation. According to China's state television, Xi stuck with his objective of "denuclearization" of the Korean Peninsula, and called for a peaceful resolution of rising tension... "We hope that the relevant parties do not adopt irresponsible actions. Under the current circumstances, this is very dangerous," Lu told reporters at a regular press briefing... Translation: Trump is strongly urged not to launch a unilateral strike on North Korea as he did on Syria without express Chinese prior approval.
