Chinese state media was not yet reporting the decision, and the White House declined to say what the source of Trump's information was. The step would amount to major progress in US efforts to cut off support for Pyongyang as punishment for its nuclear provocations. Trump has applied pressure on Beijing, North Korea's top economic patron, to end trade and financial support. "It is unacceptable that others financially support this criminal rogue regime," Trump said at the start of the talks, held at a hotel in New York, adding he was calling for "complete denuclearization" in North Korea. The executive order Trump inked just ahead of the lunch enhances Treasury Department authorities to target individuals who provide goods, services or technology to North Korea, Trump said. He added the order would also allow the US to identify new industries — including textiles, fishing and manufacturing — as potential targets for future actions.
