Burma’s human rights situation remains poor despite some noteworthy actions by the government toward reform. In April 2012, opposition leader Aung San Suu Kyi’s party swept nearly all the seats contested in a parliamentary by-election, but a large majority of seats in Burma’s lower house are controlled by the government party and the military. President Thein Sein welcomed back exiles and released nearly 400 political prisoners, but several hundred prisoners remain behind bars. While some laws have been amended, repressive laws remain. The army targeted civilians in armed conflict with the Kachin minority group. After violence erupted between Arakanese Buddhists and the long-persecuted Rohingya Muslims, state security forces took part in abuses against the Rohingya.
