US eases Burma trade ban

"President Thein Sein’s government has released hundreds of political prisoners, removed pre-publication censorship requirements for the press, and enacted a labor law that permits the formation of labor unions," it said, calling April 2012 elections mostly free. 

The U.S. is, however, maintaining a list of firms and Burmese citizens that cannot do business with U.S. citizens or entities. 

"Despite positive changes, the United States remains concerned about corruption, remaining political prisoners, continued military ties to the Democratic People’s Republic of Korea, and ethnic conflict," the State Department said.
