South Korean President Moon Jae-in on Wednesday left for Germany to attend a summit of the Group of 20 leading economies (G20) later this week, a media report said.

Moon would push to have several bilateral summit meetings on the sidelines of the G20 meet, including those with the leaders of China, Russia, Japan, India, France and Australia.

Moon showed a stiff look before boarding a presidential plane as his overseas trip followed Pyongyang's claim on Tuesday of successfully testing a new type of intercontinental ballistic missile (ICBM), Hwasong-14, Xinhua news agency reported.

This was Moon's second overseas trip since his inauguration on May 10. 

On June 29 Moon met US President Donald Trump in Washington.

The new South Korean leader was scheduled to stay in Berlin for two days at the invitation of German Chancellor Angela Merkel.

He would hold a summit meeting with Merkel during his stay in Berlin, according to the presidential Blue House. He would then move to Hamburg to attend the G20 summit meeting.
