"The steps acknowledge important change the government of Burma has made. They encourage and empower government and people to continue on the path of political and economic reform," a senior administration official said after President Barack Obama issued necessary orders in this regard.
The United States identifies Myanmar with its previous name Burma.
In his letter to the Congress, Obama said the government of Myanmar has made significant progress in number of critical areas including release of political prisoners, achieving ceasefire talks with 11 armed ethnic groups, taking steps toward removing press censorship and enabling participation of opposition parties in country's political system.
The President further said issues like fete of remaining political prisoners and ongoing conflict and human rights abuses in ethnic minority areas in Myanmar also continue to pose concerns.
"The US is committed to supporting and strengthening Burma's reform efforts to ensure that the democratic transition becomes irreversible. For this reason, I have determined that it is necessary to continue the national emergency with respect to Burma," Obama said in the letter.
