The Revolutionary Proletarian Army – Alex Boncayao Brigade engaged in peace negotiations brokered by
Eduardo Cojuangco Jr. with the government of
Joseph Estrada in 1999; a
truce was established in December 2000. This development prompted a vehement condemnation from
Filemon Lagman, who once controlled the Alex Boncayao Brigade; in a
press release he branded Arturo Tabara of the RPA and Nilo dela Cruz, the head of the ABB as "scoundrels masquerading as revolutionaries". By 2003, relations between the RPA-ABB and the Communist Party of the Philippines had deteriorated to the point where the
New People's Army, the CPP's military wing began launching attacks on the RPA-ABB. Arturo Tabara, RPM-P chairman, was assassinated in 2004 in
Manila. In April 2013, the RPA-ABB was reported to have changed its name to
Kapatiran para sa Progresong Panlipunan ("Brotherhood for Social Progress") and stated that it had renounced violence as a method of advancing its cause. Paduano resigned as national commander of the RPA-ABB and ran for Congress during the
2013 Philippine general election under the
Abang Lingkod party-list. The
National Democratic Front of the Philippines issued a statement condemning his election into the
Congress of the Philippines. As of 2016, the peace deal signed by the RPA-ABB with the Estrada administration remains to be fully implemented. Nilo dela Cruz and a group of former RPA-ABB members calling themselves "Democratic Front for Filipinism" issued a statement supporting
Rodrigo Duterte's
war on drugs, and his "revolution against the
oligarchs and the exploiters of the Filipino masses". ==References==
