Premier Li Keqiang, Republic of Korea President Moon Jae-in and Japanese Prime Minister Shinzo Abe attended a commemoration of the 20th anniversary of China-Japan-ROK cooperation at the Du Fu thatched museum, in Chengdu, Southwest China's Sichuan province, on Dec 24.

A renowned Chinese poet from the Tang Dynasty (618-907), Du Fu is also a popular historical figure among Koreans and Japanese. The poet sage lived in the cottage for almost four years, during which he wrote over 240 poems.

In the afternoon, the three leaders visited the museum together.

They also heard students from China, Japan and ROK reading Du Fu's poems in their own languages.

Du Fu, who lived in a hut, was concerned about the people and the country, the Premier said in front of the poet’s old home.

The three leaders visited the museum and attended an unveiling ceremony for a commemorative envelop marking the 20th anniversary of trilateral cooperation.

They also visited a photo exhibition there and planted an osmanthus tree together.

Calling the tree a symbol of the China-Japan-ROK friendship, Premier Li said the tree will surely grow tall and luxuriant.
