South Korea sent a document to North Korea requesting discussions on an inter-Korean video call system, a few days after the two sides reconnected hotlines, the unification ministry said on Monday.

The document is the first sent across the border via the communication channels since their restoration, a ministry official told NK News on Monday. The two Koreas announced the reestablishment of multiple hotlines last week, more than a year after North Korea “cut” the communication channels in June 2020.
