The leaders of South Korea, China and Japan said Sunday that trilateral cooperation had been "completely restored" after holding their first summit in more than three years.

South Korea President Park Geun-Hye and Chinese and Japanese premiers Li Keqiang and Shinzo Abe temporarily set aside historical animosities to discuss shared security and trade concerns during a 90-minute meeting in Seoul.

"We shared the view that trilateral cooperation has been completely restored on the occasion of this summit," they said in a lengthy joint statement issued after the meeting.
