SEOUL, May 29 (Xinhua) -- A senior official of the Democratic People's Republic of Korea (DPRK) is headed for the United States for working-level talks, South Korea's Yonhap news agency reported Tuesday.

Citing an unidentified source, Yonhap reported that Kim Yong Chol, vice chairman of the ruling Workers' Party of Korea (WPK) Central Committee, will fly to the United States Wednesday for talks with U.S. Secretary of State Mike Pompeo on a possible summit between the DPRK's top leader Kim Jong Un and U.S. President Donald Trump.

Expectations are running high for the Kim-Trump summit to be held in Singapore on June 12 as scheduled.

Trump abruptly canceled his meeting with Kim last week, but the DPRK said it was ready to sit down with the U.S. side at any time.

South Korean President Moon Jae-in held a surprise summit with Kim at the border village Panmunjom Saturday, confirming the willingness of both Kim and Trump to hold the first-ever DPRK-U.S. summit as scheduled.

Before the inter-Korean summit on Saturday, Moon met with Trump in Washington to discuss the DPRK-U.S. summit.
