Papua New Guinea's environment minister has said that given the lack of financial aid, his country may "rethink" efforts to cut logging, coal mining and even coming to meetings such as the United Nations climate summit in Glasgow.
"If they keep stalling. There's no point in returning to any future COP meetings," minister Wera Mori said.
Mori said rich and developed countries like the United States, the United Kingdom, China, Japan and the European Union must pay up and that without a meaningful agreement in Glasgow, Papua New Guinea may roll back measures they have taken to cut greenhouse gas emissions.
"We will have to decide as a country to rethink what position we have taken... in terms of logging, in terms of extracting coal and other measures," Mori said.
The minister said his country has cut back on logging, plans to ban round log exports by 2025 and hasn't issued new coal mining permits.
But if financing is not forthcoming then "we cannot be swimming around in the wilderness".
"Logging is a $US1 billion industry. We've got thousands of square kilometres of coal seam which we want to mine, extract and produce cheap power, cheap energy for our industries," he said.
"Why should Papua New Guinea make the sacrifice?"
