Chinese Foreign Minister Wang Yi says he urged his North Korean counterpart to abide by United Nations resolutions and stop provoking "the worldwide community's goodwill" with missile launches and nuclear tests.
There was no direct reaction from North Korea to Tillerson's remarks but in a statement after the USA secretary of state made his comments, Pyongyang responded robustly to the new sanctions by saying it was ready to teach the United States a "severe lesson" if it attacked.
The North said it would take an unspecified "resolute action of justice" and would never place its nuclear program on the negotiating table or "flinch an inch" from its push to strengthen its nuclear deterrence as long as US hostility against North Korea persists.
A nuclear war between North Korea and the United States is not imminent, analysts said, but the inflammatory rhetoric on both sides is increasing the risk. He said the ARF is the only regional dialogue where North Korea sends its foreign minister. "The North Korean challenge is one of them". Despite pressure from the worldwide community, Pyongyang has made no secret of its nuclear ambitions.
If enforced, the measures could lop an estimated $1 billion annually off North Korea's meager export revenue of $3 billion.
The statement said that Cayetano told Ri, "We say this in the spirit of our common goal of maintaining peace and security for our peoples".
Responding to the ICBM provocation with a show of force, the US and South Korean troops on Wednesday conducted "deep strike" precision missile drills using Army Tactical Missile System (ATACMS) and the Republic of Korea's Hyunmoo Missile II. "Neither shall we flinch even an inch from the road to bolstering up the nuclear forces chosen by ourselves unless the hostile policy and nuclear threat of the United States against North Korea is fundamentally eliminated".

"Do not violate the UN's decision or provoke worldwide society's goodwill by conducting missile launching or nuclear tests", he told the North Korean diplomat.
Last month's pair of groundbreaking tests of long-range ballistic missiles has put the continental United States in range for the first time.
Even if, in the best-case scenario, the sanctions hurt North Korea's economy and weaken its government, questions remain over what to do next.
"When the conditions are right, then we can sit and have a dialogue around the future of North Korea so they feel secure and prosper economically", Tillerson told assembled reporters in Manilla. They're only a tactic for getting Kim Jong Un's totalitarian government to end its missile advances and atomic weapons tests, and there is little evidence to suggest this newest round of economic pressure will be more successful than previous efforts.
China's patience with North Korea, its onetime close ally, appears to be running thin: Beijing agreed to recent United Nations sanctions, despite potential losses to Chinese firms doing business with North Korea and fears over destabilizing the Pyongyang regime.
The rising tensions between North Korea and the United States - the biggest foreign policy crisis Trump has faced in his six-month-old presidency - contributed to a weak open for US stocks.
The talks the North Korean foreign minister were referring to include dialogue Seoul has proposed, aiming to alleviate tensions at the demilitarized zone.
In his opening remarks for the Ministerial Meeting, Tillerson said that among the issues that have been discussed between him and the ASEAN officials are "a number of matters of mutual security interest, and a number of economic areas of interest".
