The U.S. State Department stands firm on its position that inter-Korean ties must move forward in step with Pyongyang's denuclearization process.
A State Department official, responding to an enquiry by South Korea's Yonhap News Agency, said the U.S. is aware that the two Koreas plan to open a joint liaison office in Kaesong.
The official did not comment on whether the project would be against the sanctions on North Korea, but said that the restrictions remain valid until the complete denuclearization of the regime.
The U.S. response comes after Seoul's top office rejected claims that opening an inter-Korean liaison office at the Kaesong Industrial Complex violates international sanctions.
The State Department also said the two Koreas' road modernization project needs to go hand in hand with Pyongyang's denuclearization process, according to VOA on Tuesday.
