Analysts say that North Korea, already under numerous United Nations and other worldwide sanctions, will feel some pain from the new sanctions but is not likely to return to disarmament negotiations anytime soon because of them. He's not specifying what those are.
Kim Jong-un's regime rattled Washington in July with two intercontinental ballistic missiles (ICBM) tests. "But in order to protect the worldwide non-proliferation system and regional peace and stability, China will, as before, fully and strictly properly implement the entire contents of the relevant resolution".
Tillerson and the North Korean foreign minister are expected to share a room for talks Tuesday. "We haven't really discussed that among ourselves", said Philippine acting Foreign Affairs Secretary Enrique Manalo of the USA call to minimize relations with Pyongyang. Instead, the US was represented at the dinner by Thornton, whose official title is acting assistant secretary of State for East Asia and Pacific Affairs.
Mr Wang's meeting with North Korea's Mr Ri started off cordially, with Mr Ri smiling as the two shook hands.
China is providing a welcome boost to the global campaign to pressure North Korea to halt its missile and nuclear tests. What's the loss of trade with North Korea compared to the economic bounty available in the west? There are signs that at least some factions of the Trump administration are open to negotiation.
But Washington says it will be watching closely to ensure that China doesn't ease up on the North - if and when the world's attention is diverted elsewhere.
USA officials have been adamant there will be no direct meetings with North Koreans in Manila, even among lower-level officials. China, she said, has typically cooperated with sanctions after flagrant violations only to loosen the reins over time.
The new sanctions were drafted by the U.S.in consultation with China and passed unanimously at the United Nations on Saturday.
"China and Russian Federation are playing a different game and accepted "tough" sanctions to avoid United States sanctions on their own companies".
Thornton says the USA isn't now considering China's proposal to freeze US military exercises with South Korea in exchange for the North halting nuclear development. "I don't think that the USA has a clear policy on North Korea".
"We actually had very thorough talks", Wang said, adding "The Chinese side urged the North Korean side to calmly handle the resolutions the UN Security Council just made towards North Korea and to not do anything unbeneficial towards the worldwide community such as a nuclear test".
China's foreign minister Wang Yi held a bilateral meeting with his North Korean counterpart Ri Yong Ho Sunday on the sidelines of the Association of Southeast Asian Nations (ASEAN) ministerial meetings in Manila.
A USA push to further isolate North Korea appeared to be reaping some dividends Sunday as China, Pyongyang's major benefactor, urged its outcast neighbor to make a "smart decision" and stop conducting missile launches and nuclear tests.
Wang, however, quickly added, "Of course, we would like to urge other parties like the USA and South Korea to stop increasing tensions". Given North Korea's unremitting rhetoric, it could be a quick - though limited - nuclear war.
It will be the first such meeting since U.S. President Donald Trump took office in January.
Ri said in the Monday statement that the nuclear program is for potential self-defense "in the face of a clear and real nuclear threat posed by the U.S".
Also on Sunday the foreign ministers of Asean and China adopted a negotiating framework for a code of conduct in the South China Sea, a move they hailed as progress but seen by critics as a tactic to buy China time to consolidate its maritime power.
For the USA, it was a long-awaited sign of progress for Trump's strategy of trying to enlist Beijing's help to squeeze North Korea diplomatically and economically.
"Who has been carrying out the U.N. Security Council resolutions concerning North Korea?".
Kang chimed in: "It was a very, very good outcome".
South Korea reiterated further resolutions against Pyongyang could follow if it did not pull back.
The meeting comes as the US and Asian nations join together to try to step up Pyongyang's economic and diplomatic isolation.
