The unification ministry said Friday it will seek to restore communication lines and dialogue with North Korea based on "sufficient conditions" for engagement created by last week's summit between President Moon Jae-in and U.S. President Joe Biden.

In a report to the National Assembly, the ministry also said that Pyongyang must be now thinking hard about its next steps after Moon and Biden agreed to take diplomatic and pragmatic approach in denuclearization efforts.

"The leaders of South Korea and the U.S. committed themselves to complete denuclearization and peace building on the Korean Peninsula and signaled a message for a flexible approach based on diplomacy," the ministry said. "Sufficient conditions for resumption of dialogue have been created."

"We will push to reconnect communication lines and resume dialogue between the South and the North," the ministry added. "We will make preparations for the possibility of dialogue thinking that it could happen anytime, anywhere and on any issues regardless of its format."
