The US Secretary of State Rex Tillerson says two decades of US policies to contain North Korea have failed to bear any results.Tillerson, who is in Japan on his first Asia tour, added that his trip is partly meant at finding a solution to exchange views on a new regional approach. He reiterated Washington’s commitment to the security of its allies in the Asia-Pacific region. The American top diplomat said the United States wants to expand trilateral cooperation with Japan and South Korea in the face of what he called North Korea’s provocations. Japanese Foreign Minister Fumio Kishida, for his part, said Tokyo agrees with Washington that Pyongyang’s nuclear and missile programs have not been permissible.Watch Live: http://www.presstv.com/live.htmlTwitter: http://twitter.com/PressTVLiveLeak: http://www.liveleak.com/c/PressTVFacebook: http://www.facebook.com/PRESSTVGoogle+: http://plus.google.com/+VideosPTVInstagram: http://instagram.com/presstvchannelDailymotion: http://www.dailymotion.com/presstv
