Seoul, June 29 : North Korea has completed the renovation of a tower symbolising its friendship with China as the 70th anniversary of the armistice that ended the 1950-53 Korean War approaches, Pyongyang's state media said on Thursday.

A ceremony marking the completion of the project, which was carried out upon North Korean leader Kim Jong-un's order, took place in Pyongyang on Wednesday, according to the North's official Korean Central News Agency (KCNA).

The event came as the North has been seeking to boost ties with China, its traditional ally and economic benefactor, amid global sanctions on its nuclear and missile programs, and stalled denuclearisation talks with the US, reports Yonhap News Agency.
