Chinese Prime Minister Wen Jiabao reiterated to the European Union Monday that technology transfers and financial support from developed nations were key to the success of upcoming climate change talks.

The remarks came in phone talks with European Commission president Jose Manuel Barroso, which follow last week's EU summit that agreed developing nations will need 100 billion euros (150 billion dollars) per year by 2020 to fight global warming.

According to a statement issued by China's foreign ministry, Barroso briefed Wen on the EU position and its latest climate change proposals.

"The main focus is to make detailed arrangements for reducing global warming, adaptation, technical transfers and financial support," Wen told Barroso according to the statement posted on the ministry website.

"The key to success at the meeting is to uphold the (UN Framework Convention on Climate Change) and the principle of common but differentiated obligations."

China, which has refused to commit to greenhouse gas reductions, has long held that developed nations must take on greater responsibility in addressing climate change due to their historic emissions.

During last week's summit, European leaders further called on developed countries to cut greenhouse gas emissions by 80-95 percent by 2050.

The EU needs a strong, unified line to take to Copenhagen if it is to persuade the likes of China, the United States and India to make large cuts or commitments themselves.

"The EU hopes to strengthen coordination and cooperation with China in order to ensure the success of the Copenhagen meeting," the statement quoted Barroso as telling Wen.

"The EU hopes to make common efforts with China to push cooperation to a new level."

The 27-nation bloc has prided itself on leading the fight against climate change and has already agreed to cut greenhouse gas emissions by 20 percent by 2020.

Wen told Barroso that China would incorporate climate change policy into its overall national economic plan, develop a green economy and increase its capability for fighting global warming, the statement said.
