*1. Background to Japan's Geostrategy in the Bay of Bengal*:

Our central argument is that the Free and Open Indo-Pacific (FOIP) is one of the most significant geostrategic concepts in contemporary international politics. It is an international cooperation framework developed primarily at Japan's initiative, aimed at ensuring freedom of navigation, respect for international law, state sovereignty, free trade, economic connectivity, and regional security across the Indian and Pacific Ocean regions.

Former Japanese Prime Minister Shinzo Abe introduced the idea of viewing the Indian and Pacific Oceans as a broader strategic space in his historic address to the Indian Parliament in 2007, titled *'Confluence of the Two Seas'*. In 2016, at the TICAD Summit held in Nairobi, Kenya, he formally presented the concept of a Free and Open Indo-Pacific as an important initiative of Japan's foreign policy.

The fundamental philosophy of this strategy is not to establish the unilateral dominance of any state, but rather to create a stable, secure, and prosperous region based on international law and mutual cooperation.

*2. China-US Competition and the Strategic Importance of FOIP*:

The Indian and Pacific Ocean regions are currently among the most important centres of the global economy and geopolitics. Major global energy transportation routes, international maritime trade, technology supply chains, and strategic military positions are all closely connected to this region.

China's Belt and Road Initiative (BRI), its growing influence in the South China Sea, and its expanding economic and military presence in the Indian Ocean region have created a new arena of competition among global powers.

On the other hand, the United States, Japan, India, and Australia have strengthened their cooperation to protect freedom of navigation, international law, and regional security. This collaborative framework among the four countries is known as the Quad.

However, FOIP and the Quad are not the same thing. FOIP is a broader strategic vision and framework for cooperation, whereas the Quad is a cooperative forum involving four countries. It would be inappropriate to interpret FOIP as a directly anti-China military alliance. Its economic, technological, infrastructural, and development cooperation dimensions are equally significant.

*3. The New Evolution of FOIP in 2026*:

Japan's current Prime Minister, Sanae Takaichi, announced an updated framework for FOIP in an important foreign policy address delivered in Hanoi, Vietnam, on 2 May 2026. Subsequently, on 12 October, Japan's Ministry of Foreign Affairs officially published *'The Updated Free and Open Indo-Pacific'*.

The new framework places particular emphasis on three priorities.

*First*, Economic and Technological Resilience: Making artificial intelligence, information technology, energy, critical minerals, and international supply chains safer and more reliable.

*Second*, Joint Initiatives for Economic Growth: Creating new opportunities for economic growth through public-private partnerships, investment, free trade, technology transfer, and the development of regional connectivity.

*Third*, Regional Peace and Security: Strengthening maritime security, coastal surveillance, the capabilities of law enforcement agencies, defence cooperation, and cybersecurity.

It is important to note that the new FOIP framework is not confined to military security. Rather, it places particular emphasis on economic security, technological capabilities, and the freedom of partner countries to make their own decisions.

*4. Tarique Rahman's Visit to Japan: Bangladesh's Importance in Implementing FOIP*

Against this backdrop, Bangladeshi Prime Minister Tarique Rahman's visit to Japan from 26–29 October 2026 carries special significance.

Important discussions concerning Bangladesh's position and potential took place during the summit meeting with Japanese Prime Minister Sanae Takaichi in Tokyo on 27 October.

In Japan's official statement, Prime Minister Takaichi identified Bangladesh as an important partner in implementing the updated FOIP framework. She also expressed Japan's support for strengthening Bangladesh's autonomy in decision-making and the resilience of its national capabilities.

The diplomatic significance of this statement is profound. Bangladesh is being considered not merely as a development partner, but as an important stakeholder in the broader strategic connectivity framework of the Indian and Pacific Ocean regions.

*5. From BIG-B to BIG-B for Shared Prosperity: A New Strategic Initiative*

One of the most significant outcomes of the visit is the decision to upgrade the existing Bay of Bengal Industrial Growth Belt (BIG-B) initiative and establish a new strategic cooperation framework under the name *'BIG-B for Shared Prosperity'*.

The initiative is based on four pillars—

(1). Strengthening connectivity and supply chain linkages.

(2). Enhancing resilience against natural disasters and geopolitical risks.

(3). Creating new opportunities for economic growth through public-private partnerships.

(4). Expanding cooperation for regional peace and stability.

The plan envisages bringing electricity, energy, roads, railways, airports, waterways, and special economic zones under an integrated connectivity and industrialisation framework centred on the Matarbari Deep Sea Port.

This presents a major opportunity for Bangladesh. If a regional industrial and logistics hub can be developed around Matarbari, Chattogram Port, and the country's southeastern region, Bangladesh could emerge as an important economic bridge between South Asia and Southeast Asia.

*6. One Trillion Yen in Investment and Employment Potential*:

Japan's Prime Minister has expressed the expectation that Japanese private-sector investment in Bangladesh will reach one trillion yen over the next five years. Japan's official statement has also referred to the potential creation of approximately 200,000 jobs through this investment.

If implemented successfully, this initiative could make a significant contribution to Bangladesh's industrialisation, technology transfer, skilled workforce development, and export diversification.

Furthermore, the two countries have agreed to expedite the implementation of the Bangladesh-Japan Economic Partnership Agreement (EPA). This could create new opportunities for expanding bilateral trade and investment.

*7. Maritime Security: Bangladesh's New Responsibilities and Opportunities*:

The new FOIP framework places particular emphasis on maritime security. In this regard, Japan's decision to provide patrol vessels to enhance the capabilities of the Bangladesh Coast Guard is significant.

Preventing illegal fishing, human trafficking, smuggling, piracy, and ensuring the security of maritime routes in the Bay of Bengal are important matters of national interest for Bangladesh.

Japan's assistance could help strengthen Bangladesh's maritime surveillance and law enforcement capabilities. However, the primary objective of this cooperation should be to safeguard Bangladesh's own maritime security, rather than becoming entangled in the strategic competition among major powers.

*8. The Challenge of Diplomatic Balance for Bangladesh*:

Bangladesh now faces an important diplomatic question: How can it deepen its strategic partnership with Japan while maintaining balanced relations with China, India, the United States, and other international partners?

China is an important trade and infrastructure partner of Bangladesh. India is its closest neighbour and a major regional connectivity partner. The United States is one of Bangladesh's largest export markets and an important international partner. Japan is one of the principal sources of development assistance, investment, and technological cooperation for Bangladesh.

Therefore, the fundamental principles of Bangladesh's foreign policy should be national interests, sovereignty, economic development, and strategic independence.

Partnership under FOIP does not mean joining a military alliance. Bangladesh must preserve its foreign policy independence while taking advantage of opportunities for economic and maritime cooperation.

*9. The Bay of Bengal Could Become a Strategic Asset for Bangladesh*

Tarique Rahman's visit to Japan and the announcement of the BIG-B for Shared Prosperity initiative have opened up new geopolitical and economic opportunities for Bangladesh.

Bangladesh's geographical location, maritime resources in the Bay of Bengal, Matarbari Deep Sea Port, human resources, and regional connectivity potential could position the country as an important player in the Indo-Pacific region.

However, diplomatic declarations alone will not be sufficient to turn these opportunities into reality. What is required is skilled diplomacy, realistic planning, an investment-friendly environment, maritime capabilities, technological advancement, and an unwavering commitment to national interests.

Bangladesh now has an opportunity to emerge not as an arena of competition among major powers, but as an important bridge for cooperation and economic connectivity among them.

If Bangladesh can adopt an integrated strategy combining economics, security, and diplomacy centred on the Bay of Bengal, the country will become increasingly important in shaping the future of the Indo-Pacific region—not merely because of its geographical position, but also because of its own capabilities and strategic wisdom.
