Governments are unprepared for a crucial climate change meeting in Poland later this year aimed at ensuring the full implementation of the 2015 Paris Agreement, Fiji Prime Minister Josaia Voreqe Bainimarama said this week at climate talks in Bangkok.

The talks in the Thai capital come ahead of a summit in Katowice, Poland, in December, when government ministers will meet to agree rules for implementation of the 2015 Paris climate accord.

"In three months' time we will be in Katowice, and frankly, we are not ready," said Bainimarama, who is also president of the 23rd annual Conference of the Parties to the 1992 United Nations Framework Convention on Climate Change, or COP23.
