North Korea on Wednesday resumed communication with its southern neighbor on a crucial communication channel for the first time in almost two years, The Associated Press reported.

A North Korean official said on state television that leader Kim Jong Un directed officials to revive the hotline in Panmunjom.

South Korea’s Unification Ministry said the two nations "checked technical issues of the communication line" during the 20-minute call, which started at 3:30 p.m. local time, according to CNN.

The ministry said a second call followed a few hours later, the news network added.

The reopening of the channel comes after South Korea on Tuesday proposed talks with Pyongyang that could potentially take place next week.
