The United States said on Tuesday it believed it could persuade China to impose new UN sanctions on North Korea following its latest ballistic missile test and warned that Washington would also target and "call out" countries supporting Pyongyang.

Speaking to reporters ahead of a closed-door UN Security Council meeting on the missile launch, US ambassador to the United Nations Nikki Haley also made clear that Washington would only talk to North Korea once it halted its nuclear program.

"We are willing to talk, but not until we see a total stop of the nuclear process and of any tests there," Ms Haley said. "If you are a country that is supplying or supporting North Korea we will call you out on it, we will make sure that everyone knows who you are and we will target sanctions toward you as well."
