Moreover, in response to Naypyidaw's post-2011 political and economic reforms, Australia re-established a ‘normal’ bilateral relationship with Myanmar to support democratisation and reform. In June 2016, the Australian Federal Police signed a new Memorandum of Understanding with its Myanmar counterparts aimed at enhancing transnational crime cooperation and intelligence sharing. In December 2017, the US imposed sanctions on General Maung Maung Soe, a general of Western Myanmar Command who oversaw the military's crackdown in Rakhine State. The Tatmadaw had sentenced seven soldiers to 10-year prison terms for killing 10 Rohingya men in Rakhine in September 2017. A 2019 UN report revealed the degree to which the country's military uses its own businesses, foreign companies and arms deals to support, away from the public eye, a “brutal operations” against ethnic groups that constitute “serious crimes under international law”, bypassing civilian oversight and evading accountability. In June 2020, the Tatmadaw accused China for arming rebel groups in the country's frontier areas.
