KAMPALA (Reuters) - Uganda said on Monday it would stop mediating in the conflict between the Democratic Republic of Congo and M23 rebels if the U.N. Security Council endorsed accusations that Uganda was supporting the rebels.
A report by a U.N. panel of experts leaked to Reuters last week accused Uganda and Rwanda of providing support to M23, whose insurgency has displaced half a million people in North Kivu province, which borders both countries.
The report, written for the U.N. Security Council's Congo sanctions committee, said Uganda had allowed M23's political branch to operate from Kampala in addition to providing M23 with troops, weapons, technical help, political advice and facilitation of external relations.
"We have contacted the U.N. via our diplomats in New York because we want to know whether what the media wrote about is true," junior foreign minister Asuman Kiyingi told Reuters.
"If the U.N. confirms its experts wrote these outrageous falsehoods, then we'll withdraw from our mediation role in the conflict between Congo and the M23 rebels."
Kiyingi said the allegations were already undermining the perception of Uganda as a neutral mediator.
Analysts say Uganda and Rwanda have maintained extensive commercial and military networks in Congo's mineral-rich east since the two countries sent troops into Congo twice in the 1990s and 2000s.
The Ugandan government has already denied that it supports M23, calling the allegations "rubbish, rubbish, rubbish".
Congo has demand sanctions on Ugandan and Rwandese officials funneling support to M23. The U.N. Security Council on Friday adopted a statement expressing an intention to impose sanctions on M23's leaders and those who violate a U.N. arms embargo on Congo.
Uganda has been spearheading faltering efforts by a regional body, the International Conference on the Great Lakes Region (ICGLR), to put together a 4,000-strong force to neutralize M23 and police the border between Congo and Rwanda.
M23 said this month that Ugandan President Yoweri Museveni was trying to engage it in direct talks with Congo, although Congo denied it and said it had not dropped its refusal to negotiate with the insurgents.
Kiyingi said Uganda would stop its mediation role even if the United Nations did not endorse the accusations but still imposed sanctions on M23 leaders.
"We cannot try to bring two parties to the table to talk when one is under sanctions and the other is not," he said.
