When Myanmar’s leader, Daw Aung San Suu Kyi, meets with President Obama and members of Congress...one of the items for discussion will be easing the remaining American sanctions on Myanmar. That may be a tempting move, given recent efforts by Ms. Aung San Suu Kyi to end ethnic conflict and the persecution of the Rohingya, a Muslim minority group, but it would be a mistake to lift all remaining sanctions now.  Myanmar has made important progress on democratic reform...[but] the country’s 2008 Constitution...gives Myanmar’s military the upper hand... [Some] of Myanmar’s lawmakers agree [including some in the ruling party], and they believe that sanctions are still needed to keep the pressure on military leaders... [The] remaining bans on trade and investment with Myanmar’s Department of Defense, armed groups and individuals who do business with the military, including in the lucrative gems trade, should remain in place.
