Copenhagen  - Denmark has invited 192 heads of state and government to the United Nations climate-change talks it will host next month in Copenhagen, reports said Thursday.

Danish Prime Minister Lars Lokke Rasmussen had instructed Danish embassies to issue the invitations, Danish news agency Ritzau reported.

The UN summit runs December 7-18, and according to Ritzau the heads of state and government were invited for the concluding days of December 17-18.

According to the UN, some 40 heads of state and government have signalled they intended to attend the talks including British Prime Minister Gordon Brown, French President Nicolas Sarkozy, and German Chancellor Angela Merkel.

Earlier this week, US President Barack Obama said he would attend if there were prospects for a positive outcome. The United States, along with China, is the main emitter of greenhouse gases.

Hopes for a legally binding treaty at Copenhagen have dimmed but several key countries have said there were chances of an agreement on a non-binding political framework.(dpa)
