Representatives from developing countries on Friday hailed that China's commitments to efforts to redress climate change are strong and its position on the issue fair.

They made the comments after Chinese Premier Wen Jiabao had reiterated his country's positions and principles at the United Nations Climate Change Summit here.

"I was listening to it (Wen's speech) very attentively," said Sergio Barbosa Serra, Brazil's climate change ambassador, who described it as "very impressive."

He noted that Wen mentioned the actions that china is already undertaking and the ones it proposed to take in future and its efforts to curb the per-unit carbon content of GDP despite China's dependence on coal as fuel.

"These are very ambitious targets and will be very helpful not only to this negotiation but also for the climate crisis," the ambassador added.

"It is a fair comment," said Roni Ajao, special technical assistant to Nigeria's environment minister, during an interview with Xinhua.

She said that China has done a lot toward reducing carbon emissions based on various projects.

She said that both China and Nigeria are developing countries, which have a lot of socio-economic issues to deal with such as poverty and high population.

She said what the developed countries accomplished in terms of their development was achieved over centuries, while what China and other developing countries are trying to do is to develop at a faster rate of growth.

"Developed nations can't impose the same kind of conditions on developing nations, because it is unfair and unequal," she said.

The assistant agreed with Wen's viewpoint that the two-track process is "fundamentally important" to developing nations. The signing of a legally-binding agreement is also important to both China and Africa, she added.
