WASHINGTON, May 3 (Xinhua) -- The U.S. State Department said here on Friday that U.S. Special Representative for the Democratic People's Republic of Korea (DPRK) Stephen Biegun will travel to Japan and South Korea to discuss the DPRK-related issue.

According to a statement, "Biegun will travel to Tokyo May 7-8 and Seoul May 9-10 to meet with Japanese and R.O.K. officials to discuss efforts to advance the final, fully verified denuclearization of North Korea."

The second summit between DPRK's top leader Kim Jong Un and U.S. President Donald Trump in late February failed to reach a deal on the denuclearization of the Korean Peninsula.

Choe Son Hui, vice minister of the DPRK's Foreign Ministry, said recently that Pyongyang's determination for denuclearization of the Korean Peninsula remains unchanged if Washington takes a new stand in future negotiations.

"When the time comes, we will put it into practice. But this is possible only under the condition that the U.S. changes their current method of calculation and formulates a new stand," said Choe.

"We could wait until the end of this year to see whether the U.S. makes a courageous decision," the vice foreign minister said.
