From May 6 to 14, 2025, a delegation of five memb from the East Sea Institute, Diplomatic Academy of Vietnam (DAV), joined the 19th official visit to the Truong Sa (Spratly) Archipelago and the DK1 offshore platforms. This year’s 19th mission included more than 190 representatives from the Hanoi municipal government, the Ministry of Industry and Trade, local authorities, socio-political organizations, businesses, and academic institutions. The visit carried special meaning as it coincided with the historic month of May—marking the 135th birth anniversary of President Ho Chi Minh and the 70th anniversary of the founding of the Vietnam People's Navy.
