PYONGYANG/SEOUL - Kim Jong-un, top leader of the Democratic People's Republic of Korea (DPRK), said Tuesday that he would push forward the denuclearization of the Korean Peninsula and was ready to meet with US President Donald Trump at any time.

We could be left with no choice but to seek a new way if the US does not make good on its promises, misjudges our patience, while seeking to force things unilaterally and clinging to sanctions and pressure

"I am always ready to sit down again with the US president at any time and will make efforts to produce an outcome that the international community would welcome," Kim said.

In his New Year speech broadcast on the state-run television, he stressed his determination to work to build new relations with the United States, establish lasting peace on the Korean Peninsula and seek "complete denuclearization," on the condition that the United States takes corresponding measures.

"We could be left with no choice but to seek a new way if the US does not make good on its promises, misjudges our patience, while seeking to force things unilaterally and clinging to sanctions and pressure," Kim warned.
