The United Nations released the Beijing Declaration yesterday, calling for strengthened international cooperation and improved technology transfers to battle climate change.

The declaration was issued at the end of a high-level conference that opened on Friday, co-organized by China and the UN, attended by more than 600 people including 30 ministerial officials and four UN agency heads.

The document stated that international cooperation was very important, as climate change had affected every aspect of life and no country could tackle it alone.

A more comprehensive mechanism of international cooperation should be established to address the challenge, covering all stages of technology development, transfer and application, it said. The participants agreed the challenge should be addressed, based on "common but differentiated responsibilities" and respective abilities.

The event was held in the run-up to the next conference of the parties to the UN convention, to be held in Poznan of Poland next month.
