Representatives of nearly 200 countries will gather in Montreal on Dec. 5 to secure a "post-2020 framework" to protect habitats and ecosystems and ensure the sustainable and equitable use of biological resources.

Zhou Guomei, head of the international department of the environment ministry, told reporters that negotiations so far had not been "plain sailing" but focused on an ambitious deal that was "also pragmatic, balanced, feasible and achievable".

Originally set to be held in China's southwestern city of Kunming, the meeting, known as COP15, was relocated this year because of tough zero-COVID curbs. China will continue to serve as president.

In last year's first phase of talks, more than 100 nations signed the "Kunming Declaration" for urgent action to include biodiversity protection in all sectors of the global economy. But they were unable to reach consensus on issues such as funding conservation in poorer countries.

Zhou said there were still differences on a number of issues, and success would depend on an implementation mechanism for resources and financial support to be mobilised.

A previous biodiversity pact signed in Aichi, Japan, in 2010, set 20 targets to try to slow biodiversity loss by 2020. None of those targets was met in full.

Countries need to "fully consider" the attainability of any new targets, said Cui Shuhong, head of the ministry's natural ecology department.

"We should learn fully from the experience and lessons during the implementation of the Aichi targets, not only to boost the ambition and confidence in global biodiversity conservation, but also to be down-to-earth and realistic," he added.
