SEOUL - The Republic of Korea (ROK) and the Democratic People's Republic of Korea (DPRK) restored their cross-border communication lines that had been severed for over a year, the ROK's presidential Blue House said Tuesday.

The Blue House said in a statement that the two Koreas decided to resume their direct communication hotlines as of 10:00 am local time (0100 GMT) Tuesday.

The military authorities of the ROK and the DPRK reopened their military communication lines and put them back to normal operations from 10:00 am (0100 GMT), the ROK's defense ministry said in a separate statement Tuesday

All of the inter-Korean communication lines had been severed since June last year when the DPRK cut them off in protest against Seoul's failure to stop civic activists from sending anti-Pyongyang propaganda leaflets into the DPRK.

According to the statement, the ROK's President Moon Jae-in and DPRK top leader Kim Jong Un have exchanged personal letters several times since April to communicate about issues on restoring inter-Korean relations.

Moon and Kim agreed first to restore the severed inter-Korean communication lines, the statement noted.

The two leaders also agreed to restore mutual trust and enhance ties as early as possible.

Also reporting the news on Tuesday, the Korean Central News Agency (KCNA), the official news agency of the DPRK, said the restoration of the communication liaison lines "will have positive effects on the improvement and development of the north-south relations". The DPRK is also referred to as North Korea.

Meanwhile, the military authorities of the ROK and the DPRK reopened their military communication lines and put them back to normal operations from 10:00 am (0100 GMT), the ROK's defense ministry said in a separate statement Tuesday.

Fixed-line phone calls through the fiber-optic cable and faxing to exchange documents are currently under a normal operation, the ministry noted.

From Tuesday afternoon, the military authorities of the two Koreas planned to restart their regular phone calls twice a day at 9:00 am (0000 GMT) and 4:00 pm (0700 GMT) local time.

The western military hotline across the inter-Korean border worked normally, but some technical problem was found in the eastern hotline, the ministry said.

The ministry said the restored hotline would substantially contribute to the defused military tensions on the Korean Peninsula.
