Rebel ethnic armed groups in Myanmar have formed a 13-member nationwide ceasefire coordination group to make peace deal with the government, according to an announcement of the Ethnic Armed Groups Conference available Sunday.

A framework agreement on peace deal reached at the closing of the four-day conference on Saturday in Laiza, Kachin state, is expected to be presented during further talks with the government's central peace making group on coming Monday in Myitgyina, the capital of Kachin state.

However, the armed groups, in a post-conference announcement, criticized the government for its continued military offensive against the armed groups-controlled areas amid talks.

A total of 17 ethnic armed groups signed an 11-point framework agreement among themselves at the closing of the four-day conference in the border town of Laiza, northernmost Kachin state, for negotiation for a nationwide ceasefire deal with the government.

The agreement mainly called for holding political dialogue with the government within months after the planned signing of a nationwide ceasefire agreement with the government.

The framework agreement also includes laying down a political roadmap acceptable by both sides, keeping promise for holding political dialogue, trust building and its implementation.

The Laiza peace conference of leaders of the ethnic armed groups, which began on Wednesday, mainly discussed nationwide ceasefire, political dialogue and establishment of a federal union system.

The conference was organized by the Kachin Independence Organization and participated by 17 other armed groups including the United Nationalities Federal Council, the Kayin National Union, the Restoration Council of the Shan State Army (RCSS), the Democratic Kayin Buddhist Army and the New Mon State Party.

Of them, the RCSS failed to join the signing, while the United Wa State Army and National Democratic Alliance Army based in Mongla, eastern Shan State, were absent from attendance.

However, the two absent armed groups promised to join the follow-up talks between the government's central peace making group and the ethnic armed groups slated for Monday and Tuesday in Myitgyina.

The upcoming Myitgyina talks are expected to work out a comprehensive ceasefire paper for the final signing of a nationwide ceasefire accord, observers here said.
