Indonesian President Joko "Jokowi" Widodo has urged developed countries to commit to their pledge to provide financing for poorer countries to reduce greenhouse gas emissions at this month's U.N. climate conference.

Rich countries have missed a target to raise $100 billion a year to support developing countries in their climate action projects, which experts say could break down trust at the Oct. 31-Nov. 12 COP26 conference in the Scottish city of Glasgow.

"It's impossible if we don't get funding help. If we don't have the technology, it's also difficult," Jokowi said Tuesday after planting a patch of mangrove in the village of Bebatu on Borneo island.
