Vietnam's president Truong Tan Sang on visit to Washington
Sang aims to improve trade and security ties, but will face questions about human rights
Vietnam's president is starting a rare visit to Washington to boost trade and security ties between the former war foes, but activists urged the United States to press him on human rights.
President Truong Tan Sang becomes only the second Vietnamese head of state to visit the White House since the countries normalised ties.

He was due to meet business leaders and Secretary of State John Kerry.
US officials said Barack Obama hoped to work with Sang on trade, as Vietnam is one of a dozen nations negotiating the ambitious TransPacific Partnership, and on global efforts to fight climate change.
The two nations have steadily boosted military co-operation, with Vietnam worried over what it sees as assertive claims to disputed territories by China.
Obama has put a priority on Southeast Asia, seeing the economically growing and mostly US-friendly region as neglected in the past. Sang will be the fourth Southeast Asian leader at the White House this year.
Danny Russel, the top US diplomat for East Asia, called Southeast Asia "perhaps our most vibrant, our most dynamic region" in Asia or even the world, hailing Sang's visit as "quite a historic milestone".
