YANGON, Sept. 9 (Xinhua) — Myanmar State Counselor Aung San Suu Kyi will pay an official goodwill visit to the United States soon, said an official announcement Friday without specifying the date of her visit.

Expected in days, Suu Kyi's second visit to Washington at the invitation of U.S. President Barack Obama, comes nearly four years after her first one in 2012.

Myanmar-U.S. relations started to improve in 2012 with President Obama having visited the country for two times in November 2012 and November 2014 and then Myanmar President U Thein Sein made a reciprocal visit to the White House in May 2013.

The U.S. officially began lifting some sanctions after a civilian government was formed in 2011. In December 2015, the U.S.  temporarily lifted such restrictions as general license 20 for trade transactions through airports and harbors for six months.
