Rwandan President Paul Kagame said on Friday he was unsure whether a US-brokered peace deal would hold with neighbouring Democratic Republic of Congo .
The agreement calls for Rwandan troops to withdraw within 90 days from eastern Congo, where the United Nations says they are supporting M23 rebels who seized the regions two largest cities earlier this year.
Rwanda denies helping M23 and says its forces are acting in self-defence against Congos army and ethnic Hutu militiamen linked to the 1994 Rwandan genocide, including from the Democratic Forces for the Liberation of Rwanda FDLR.
Kagame told reporters Rwanda was committed to implementing the deal but that it could fail if Congo did not live up to its promises to neutralise the FDLR.
If the side that we are working with plays tricks and takes us back to the problem, then we deal with the problem like we have been dealing with it, Kagame said.
