The memorandum of understanding (MOU), signed in Tokyo in the presence of Vietnam's Party General Secretary and State President To Lam, establishes a long-term cooperation framework covering an expected total investment of USD 1 billion.
The agreement also marked the launch of MViSTA, a submarine cable system connecting Vietnam with Malaysia, Singapore and Thailand.
The MOU covers four key areas: developing new submarine cable systems linking Vietnam with international markets, including Japan; investing in digital and AI and superintelligence (SI) infrastructure, such as data centres, digital parks and computing facilities; mobilising financial resources and international partners; and transferring technology, adopting international operating standards and developing skilled workers.
Under the agreement, Stavian Group will lead project development and investment procedures in Vietnam, while Midas Capital will help mobilise capital, technology partners and institutional investors in Japan and other international markets.
A key project unveiled at the event, MViSTA is an open submarine cable system spanning approximately 2,500km and linking Vietnam with Malaysia, Singapore and Thailand.
With a designed capacity of 400 terabits per second (Tbps) across 16 fibre pairs, the system aims to increase international data transmission capacity, diversify connectivity routes and support the region's data centre, cloud computing and AI and SI ecosystems.
Its strategic investors include Stavian Group of Vietnam, Midas Capital of Japan, OMS Group of Malaysia and LitUp of Singapore.
Alongside MViSTA, Stavian Group, through its subsidiary Stavian Hightech Infrastructure JSC, is developing Stavian Digital Park (Stavian DP), a dedicated digital technology zone covering approximately 300 hectares in Ho Chi Minh City.
The park is designed to accommodate hyperscale cloud providers, AI and SI data centres, and businesses requiring advanced digital infrastructure.
Its feasibility study is funded by the US Trade and Development Agency (USTDA) and led by Cushman & Wakefield, with APTelecom serving as a specialist telecommunications subcontractor.
The two projects are intended to complement each other by connecting international data transmission infrastructure with data centres and AI and SI computing capacity, creating an integrated ecosystem designed to meet international standards and support future expansion.
The MOU also reflects the two companies' commitment to implementing Politburo Resolutions No. 57-NQ/TW and No. 68-NQ/TW and supporting the development of the Vietnam-Japan Comprehensive Strategic Partnership.
Speaking at the signing ceremony, Dinh Duc Thang (Tony), chairman of Stavian Group, said digital infrastructure was fundamental to the development of superintelligence, the digital economy and national competitiveness.
"Through our cooperation with Midas Capital and international partners, Stavian Group aims to develop submarine cable, data centre and AI and SI infrastructure projects with connectivity and scalability aligned with international standards," he said.
The partnership further expands Stavian Group's technology and infrastructure activities across its four core business pillars: industry, technology, energy and trade.
