The US special envoy will visit North Korea on Wednesday

The United States special envoy for North Korea, Stephen Biegun, will travel to Pyongyang Wednesday before the second summit between Donald Trump and Kim Jong-Unsaid the state department Monday.

In addition to preparations for the summit, Biegun and his North Korean counterpart, Kim Hyok Chol, will also see ways to "advance the commitments" of Trump and Kim at their first summit in Singapore: "Complete denuclearization, transform relations between the United States and the DPRK and bring lasting peace to the Korean peninsula," said a statement.

In an interview for the channel CBS on Sunday, Trump announced that he had already set the date and venue for his second summit with Jong Un, leader of the People's Republic and the Democratic Republic of Korea (DPRK, official name), and stated that he would probably communicate them before or during his State of the Union speech on Tuesday.

The meeting between the two leaders will surely take place at the end of February in Vietnam, which the government indicated a few days ago that it was beginning preparations to host the meeting.

After their first summit, held June 12 in Singapore, Trump and Kim signed a document in which the North Korean leader showed willing to work for the "denuclearization of the Korean peninsula".

But negotiations have not progressed since then and Washington and Pyongyang can not agree on the real meaning of this statement.

Last week, the director of the US National Intelligence, Dan Coats, considered before the Congress "North Korea is unlikely to be willing to give up all its nuclear weapons and production capabilities."
