Prime Minister Narendra Modi, who arrived in Vietnamese capital Hanoi on Friday night, was given a ceremonial welcome, on Saturday morning.
Modi, who is the fourth Indian Prime Minister to visit Vietnam during past about 50 years, began his day by paying homage to national heroes and martyrs at their monuments.
After national anthems of both India and Vietnam were played by the armed forces band, dressed in sharp white with gold tassels and black gum boots, the prime minister inspected a guard of honour by the three armed forces of the host country.
Immediately afterwards Modi, in white churidar kurta with grey jacket, was taken to the humble traditional stilt house near the palace where Vietnam's beloved leader Ho Chi Minh lived intermittently between 1958-1969. He was shown the place by the Vietnamese president.
India and Vietnam signed 12 agreements in a wide range of areas covering defence, IT, space, double taxation and sharing white shipping information, signalling a strong upward push in their strategic ties.
The agreements were signed by officials of the two sides in presence of Prime Minister Narendra Modi and his Vietnamese counterpart Nguyen Xuan Phuc here.
"12 for togetherness! India & Vietnam sign a dozen agreements for further strengthening the Strategic Partnership," External Affairs Ministry Spokesperson Vikas Swarup tweeted.
The pacts included agreement on exploration and uses of outerspace for peaceful purposes, agreement on avoidance of double taxation, health cooperation, IT cooperation, cyber security and agreement on contract and design, building of boat in India, equipment supply and technology transfer.
