The United States and North Korea on Sunday held working-level talks at the border village of Panmunjeom in the Demilitarized Zone, according to South Korean media reports.

The talks are believed to have been held to coordinate the agenda of an upcoming visit by U.S. Secretary of State Mike Pompeo to North Korea, according to the reports.

The delegations were led by North Korean Vice Foreign Minister Choe Son Hui and U.S. Ambassador to the Philippines Sung Kim, the Yonhap news agency reported, quoting diplomatic sources. It said the meeting lasted about an hour.

According to MBC television, Kim arrived in South Korea on Friday and headed to Panmunjeom on Sunday in the U.S. ambassador's car.

They previously met at the same location in June to coordinate for the summit between their leaders held in Singapore on June 12.

The Financial Times reported Thursday that Pompeo will visit Pyongyang this week to press forward with the Trump administration's efforts to force North Korea to denuclearize.

The report said Pompeo had canceled a planned meeting with his Indian counterpart, due in Washington on July 6, in order to fly to North Korea.
