After the United Kingdom made the first move by pledging to boost its climate funds to help developing economies fight climate change, other developed economies have been called on to follow suit swiftly.

Several other countries have shown a willingness and made budget plans to provide funds after a three-year climate change fund runs out at the end of this year, Xie Zhenhua, China's top climate change official told reporters on Wednesday in Doha. Xie didn't give more details.

The UK announced on Wednesday it would boost its climate funding for the next two years to 1.8 billion pounds ($2.9 billion), a 40 percent increase over its contribution to the Fast Start Finance during the 2010-12 period.
