Things 'going very well,' Trump says after talk with South Korean president Moon Jae-in

US President Donald Trump said on Saturday that he had spoken with South Korean President Moon Jae-in and preparations for a meeting with North Korea were being set.

"Just had a long and very good talk with President Moon of South Korea. Things are going very well, time and location of meeting with North Korea is being set," Trump said on Twitter.

Trump added that he had also spoken with Japanese Prime Minister Shinzo Abe to inform him of ongoing negotiations.

North Korea's state news agency on Saturday called the inter-Korean summit a turning point for the Korean peninsula, while US President Donald Trump said he would maintain sanctions pressure on Pyongyang ahead of his own unprecedented meeting with Kim Jong Un.

The North's KCNA news agency separately released the joint statement North Korean leader Kim Jong Un and South Korean President Moon Jae-in presented on Friday after the first summit in more than a decade between the two Koreas.

Kim and Moon had pledged to work for "complete denuclearisation" of the Korean peninsula and agreed on a common goal of a "nuclear-free" peninsula.

"At the talks both sides had a candid and open-hearted exchange of views on the matters of mutual concern including the issues of improving the north-south relations, ensuring peace on the Korean Peninsula and the denuclearisation of the peninsula," KCNA said, reporting that the night wrapped up with a dinner with an "amicable atmosphere overflowing with feelings of blood relatives."

A day after the meeting between Kim and Moon produced dramatic images and a sweeping declaration of goodwill, South Korean media were replaying striking scenes of the two leaders and North Korea's main state newspaper published a multi-page spread with more than 60 photos from the visit.

On Saturday afternoon, North Korean state TV broadcast its first footage of the summit.
