The US today warned of using military force in response to North Korea's launch of a ballistic missile and also blasted China and Russia for holding the hands of Kim Jong Un. <br/><br/>US Ambassador to the UN Nikki Haley said at an emergency Security Council meeting in the United Nations yesterday that the actions by Pyongyang made the world a more dangerous place. She said, the illegal missile launch was not only dangerous, but reckless and irresponsible.<br/><br/>Calling out on China, Ms Haley said much of the burden of enforcing UN sanctions against North Korea rests with Beijing as 90 per cent of trade with North Korea is from China. While she said US will work with China, at the same time she warned that some countries are allowing and even encouraging trade with North Korea in violation of UN Security Council resolutions.
