Ministers from the Group of 20 nations have gathered in Bali, Indonesia, for a meeting on the environment and climate change.
Japan's Environment Minister Nishimura Akihiro is attending the meeting, which opened on Wednesday.
Indonesia's environment minister, Siti Nurbaya Bakar, stressed it is their responsibility to be part of the solution. She urged the participants to build bridges, not walls, and promote common interests, not self-interest.
The event is one of a series of G20 meetings this year in Indonesia.
The ministers will discuss issues such as extreme weather and disasters blamed on climate change, and plastic waste in the oceans.
Japan and Western nations are expected to criticize Russia over its invasion of Ukraine.
Differences between Russia and the West were highlighted at G20 ministerial meetings in July.
It remains to be seen whether they can draw up a joint statement and agree to work together on climate change and other matters of global concern.
