"The North appeared to show a measured response to Trump's visit.... There was no threat of military action and the North's insults against Trump seemed to be reduced," Baik Tae-hyun, ministry spokesman, told a regular press briefing.

Baik declined to give reasons for the government's assessment but cautious optimism for possible talks between the US and the North has risen as North Korea has refrained from provocations for about 60 days.

Joseph Yun, the top US nuclear envoy, said last month if North Korea halted nuclear and missile testing for about 60 days, it would be the signal indicating that the US needs to resume direct talks with Pyongyang, according to The Washington Post.

Trump said in Seoul that it makes sense for North Korea to come to the table and "make a deal," saying that he has seen "a lot of progress" in efforts to make Pyongyang give up nukes. (Yonhap)
