The United States has urged all countries to cut off regional and trade relations with North Korea, which recently conducted a ballistic missile test. Speaking at the UN Security Council, US Ambassador Nicky Haly said US President Trump had asked China to disconnect oil supplies to Pyongyang. He said that the US did not like contradictions, but warned that if the war erupts, North Korea's regime would be "totally destroyed." This warning has been issued following a North Korean launch of ballistic missile test from the South Pyongyang region. North Korea claims that the launch of the rocket last Wednesday reached 4,475 km high - 10 times higher than the International Space Station - it is capable of re-entering the Earth's atmosphere. However, this claim has not been proven. Experts suspect the country's ability to set up such technology. North Korea leader Kim Jong-thu has said that this test is "not cheap" and "a big break". US
