As a political and social organization, the Ba Ria-Vung Tau Union of Friendship Organizations has worked with agencies, other organizations, and member associations to improve and diversify the province’s people's diplomacy activities over the years.

It has worked with 34 countries and territories to exchange friendship delegations and non-governmental aid, established close ties with the Consuls General of Russia, Japan, Cuba, Laos, Thailand, and France, and maintained cooperation with domestic organizations and localities.

The Union has raised money to support the regions of neighboring countries severely affected by natural disasters in order to promote the friendship among peoples.

Ba Ria-Vung Tau has signed a cooperation agreement with Russia’s Nenetskiy autonomous region under which both have organized many exchange activities, including a Cultural Day of the Nenetskiy Autonomous Region in Ba Ria-Vung Tau province.

Under a friendship and cooperation agreement, Ba Ria-Vung Tau and Italy's Veneto region have boosted exchanges in numerous areas including maritime transport, port logistics, food processing, education, training, tourism, promotion of cultural and environmental heritages, and energy, especially renewable energy.

The two sides have also cooperated in information sharing on trade and investment, exchanged trade and business delegations, and encouraged delegations to attend exhibitions and other events held by each party.

Meetings will be organized annually to evaluate the effectiveness of cooperation exchanges.

In 2017, the Ba Ria-Vung Tau People's Committee and the government of the Republic of Bashkortostan, Russia, signed cooperation agreements in economics, trade, science, technology, and culture. To implement the Free Trade Agreement between Vietnam and the Eurasian Economic Union (EAEU), the two localities have organized the Ba Ria-Vung Tau-Bashkortostan Business Forum and opened a showroom to display Ba Ria-Vung Tau products in Ufa city.

The two localities are planning to construct high-end resorts and promote their tourism potential to attract more tourists from Ba Ria-Vung Tau to Bashkortostan and vice versa.

More art troupes will be exchanged to help the two peoples better understand each other’s culture and history.

Bashkortostan will help students from Ba Ria-Vung Tau study petroleum and medicine at universities in Ufa City, according to a working visit by Ba Ria-Vung Tau authorities to Bashkortostan last year.

Visits and exchanges have been held in Ba Ria-Vung Tau for delegations of the Russian government and associations of veterans, teachers, and students. Outstanding students from Ba Ria-Vung Tau province have had opportunities to visit Russia and exchange with Russian children.

These exchanges and cooperation activities have helped people of other countries better understand the Vietnamese people and Vietnam’s Party and State policies, and helped Ba Ria-Vung Tau take advantage of international support for the province's socio-economic development programs, especially in healthcare, education, humanitarian relief, social sponsorship, environmental protection, and climate change.

Joint venture projects between Ba Ria-Vung Tau and international economic groups have been set up: a joint venture for oil and gas exploration in Russia’s Nenetskiy autonomous region, the Vina-Japan Shirogane Logistics Company, the Vina Kyoei steel production joint venture, and the Vietnam Posco Steel Company.
