U.S. Ambassador to Armenia John Heffern is on a visit to the United States for meetings with representatives of the Armenian-American Diaspora community.

After five days spent in Los Angeles, Heffern left for San Francisco to attend ArmTech Congress 2012, annual high-tech industry business forum.

“Very useful 5 days in LA. Listened and learned a lot. Off to SF for ArmTech now. US-Armenia IT cooperation is transforming Armenia,” he tweeted.

ArmTech will be also attended by the Armenian delegation headed by Prime Minister Tigran Sargsyan.
