Denmark highly appreciates China's efforts to push for an ambitious, comprehensive, detailed and fair agreement in Copenhagen, said Danish ambassador to China Jeppe Tranholm-Mikkelsen on Wednesday.

"We warmly welcome the decision by Premier Wen Jiabao to attend the climate change summit and the decision on a CO2 intensity target by the Chinese government," said the ambassador in a written interview with Xinhua.

"We see these decisions as a clear expression that China is committed to reaching an ambitious, comprehensive, detailed and fair agreement in Copenhagen," he added.

The UN Climate Change Conference opened on Monday in Copenhagen, where delegates from more than 190 countries will try to seal a deal that is expected to slow rising global temperatures that could bring more heat, expanding deserts, floods and rising sea levels.

Chinese Premier Wen Jiabao would attend the conference at the invitation of Danish Prime Minister Lars Lokke Rasmussen, according to the Foreign Ministry.

"The overall aim of the climate change summit is to put the world onto a low carbon path so that we can limit the increase in temperatures to a maximum of 2 degrees Celsius," said the ambassador.

"This aim can only be achieved if all major countries and groups of countries contribute. The problem is a truly global one and cannot be solved by neither developed nor developing countries alone," he added.

He called on countries to contribute in different ways to a solution in accordance with the principle of common but differentiated responsibilities and respective capabilities.

Though difference and difficulties ahead, the ambassador said he was firmly convinced that an "ambitious" and "comprehensive" global agreement would be possible for the world to reach.

"The announced participation of more than 100 heads of state and government, including Premier Wen Jiabao and U.S. President Barack Obama, provide a very strong political momentum towards success," he said.

As host country, Denmark would provide the framework and facilitate agreement at Copenhagen, he said, calling on all participating parties to contribute to a deal.

With regard to China's efforts, Jeppe said his government highly appreciates China's positive approach to the negotiations on climate change, as well as the close contacts and consultations between the Chinese negotiating team, experts and their counterparts from other parties.

The ambassador said China's position has become more and more constructive over the last couple of years.

He called the Chinese National Plan for Coping with Climate Change that unveiled in 2007 was a "milestone" for China and for the world, which demonstrated that China acknowledges that man-made climate change is a problem and that China wants to be part of the solution.

China has shown good progress in achieving the goals set out in the National Plan over the past two years, said the ambassador, adding China is well underway to achieve both its energy intensity and renewable energy targets by 2010.

"China's success is very encouraging and indicates that the country may be able to achieve even more ambitious results in the future," he said.
