South Korea and the Democratic People's Republic of Korea (DPRK) on Friday agreed to actively cooperate in upgrading the direct communications line between the two sides.

The agreement was reached following the working-level talks on upgrading the decrepit communications line across the border, which were held earlier in the day at the inter-Korean liaison office in the DPRK's border town of Kaesong.

During the talks, the two sides shared a view that the decrepit direct communications line between the authorities of the two Koreas needed to be replaced with optical cables. The current line is made of copper.

South Korea and the DPRK agreed to continue consultations on the issue, according to Seoul's unification ministry.

The five-member South Korean delegation was led by Chung Chang-min, a director-general-level official with the Ministry of Science and ICT. The DPRK delegation was represented by Ri Yong Min, a senior official in charge of communications affairs.
