He said, there can only be a diplomatic solution to the situation, achieved through a process of sincere dialogue.<br/><br/>North Korea said, it has agreed to regular communication with the UN.<br/>Mr Feltman's visit came after the US and South Korea launched their biggest-ever annual joint air exercises. <br/><br/>The exercises were held a week after North Korea test-fired a powerful new intercontinental ballistic missile that experts say is capable of reaching the US.

North Korea and the United Nations have agreed to communicate regularly. North Korea's state run news agency on Saturday reported that this latest development is a result of a senior U.N. official's recent visit to the isolated nation. <br/><br/>Jeffrey Feltman, the U.N.'s under-secretary-general for political affairs, visited North Korea this week, holding meetings with Foreign Minister Ri Yoing Ho and Vice Foreign Minister Pak Myong Guk. Before leaving for Pyongyang, Mr Feltman held talks in China, North Korea's historic ally and main trading partner.<br/><br/>Feltman's visit came right after the U.S. and South Korea launched their biggest-ever, annual joint air exercises. <br/><br/>The U.S. and South Korean exercises, however, came a week after North Korea test-fired a powerful new intercontinental ballistic missile that experts say is capable of reaching the U.S.
