The Mexican Foreign Ministry on Sunday denied that U.N. peacekeeping troops will be present during an upcoming U.N. climate conference set to be held in Mexico.

Based on international rules for these kinds of events, there will only be U.N. security staff inside the place where the climate meeting will be held, the ministry said in a statement.

The annual Conference of the Parties to the U.N. Framework Convention on Climate Change (COP16) is to be held in Cancun, Mexico, from Nov. 29 to Dec. 10.

During the conference, the zone will be guarded by municipal, state and federal police, according to the statement.

Some media reports said on Saturday that U.N. peacekeeping troops would be in charge of security during the climate conference.

According to U.N. rules, peacekeeping troops are tasked with performing operations to guarantee peace in those nations which request it in advance.
