It is rumoured that the Kachin Independence Army (KIA) has sent a letter telling the United Nationalities Federation Council (UNFC), which is in peace talks with the government, that it is leaving the bloc.
Radio Free Asia and Irrawaddy reported on May 6 that the letter was signed by La Nan, general secretary of the KIA.
The KIA, Shan State Progressive Party, Karenni National Progressive Party, New Mon State Party, Arakan National Council, Lahu Democratic Union and Wa National Organisation are members of the UNFC.
The UNFC submitted a nine-point proposal of demands before it would sign the 2015 national ceasefire agreement, which has been discussed five times, with the most recent meeting between the two sides in Chiang Mai, Thailand, on April 28. A separate rebel alliance, the Union Political Dialogue Negotiation Committee, which is led by United Wa State Army, has said it cannot accept the 2015 ceasefire.
