More than 300 business, government and development leaders gathered in Singapore for the second Global Business Summit on Belt and Road Infrastructure Investment to Accelerate the SDGs, putting sustainable infrastructure, responsible AI, clean energy and sustainable finance at the center of the next phase of cross-border investment. The summit also produced a series of private-sector-led partnerships aimed at translating infrastructure cooperation into measurable progress toward the UN Sustainable Development Goals.

Infrastructure investment is increasingly being judged by more than its ability to connect cities, move goods or generate economic activity. The resilience of those assets, their environmental footprint, their social impact and the technology embedded within them are becoming equally important.

That shift was central to the Second Global Business Summit on Belt and Road Infrastructure Investment to Accelerate the SDGs, held in Singapore under the theme “Connect for Better World.”

Organized by the UN Global Compact’s Sustainable Infrastructure for the Belt and Road Initiative to Accelerate the SDGs Action Platform, with the UN Global Compact Network Singapore as co-organizer, the summit brought together more than 300 senior representatives from international organizations, businesses, civil society, academia and think tanks.

Rather than focusing solely on infrastructure construction, the event centered on how cross-border investment can support the 2030 Agenda for Sustainable Development.

The summit resulted in a declaration outlining business priorities across sustainable infrastructure, responsible AI, just energy transition, resilient global supply chains, sustainable finance, women’s and youth empowerment in the digital era, and international cooperation in traditional medicine.

It also launched expert groups focused on sustainable energy and sustainable digital infrastructure, alongside 12 SDG-linked initiatives covering areas including green mining, carbon-footprint standards for electricity, biodiversity, ocean protection, sustainable transport and women’s microenterprise development.

Infrastructure Moves Beyond Physical Connectivity

The summit reflects a broader change in how infrastructure is being conceived.

Roads, ports, power systems and logistics networks remain fundamental to economic development, but digital infrastructure is now equally important to the functioning of modern economies.

Cloud systems, telecommunications networks, data centers, digital public infrastructure and AI-enabled services increasingly sit alongside physical infrastructure as strategic assets.

That creates a more complex investment landscape.

Infrastructure projects must increasingly account for climate resilience, energy efficiency, digital security, data governance and long-term operating costs.

The summit’s decision to create an expert group for sustainable digital infrastructure recognizes that connectivity is no longer exclusively physical.

For businesses and investors, this could open opportunities across renewable energy, digital infrastructure, intelligent transportation, resilient supply chains and technologies designed to reduce resource consumption.

Responsible AI Becomes Part of Infrastructure Policy

Responsible AI was another prominent theme in the summit declaration.

AI is moving rapidly into infrastructure planning and operations, from forecasting electricity demand and optimizing transport networks to monitoring environmental conditions and managing industrial assets.

Yet deploying AI at infrastructure scale introduces questions around data quality, accountability, cybersecurity, transparency and access.

The summit’s focus on responsible AI therefore places governance alongside technological deployment.

For companies operating across multiple countries, this is particularly relevant. AI systems used in infrastructure often depend on data collected across jurisdictions, while their decisions can affect public services, energy systems, transport networks and supply chains.

The emerging expectation is that AI adoption should be paired with safeguards that make systems more transparent, accountable and appropriate for their intended use.

Clean Energy and the Next Phase of the Transition

Climate and energy were also central to the summit’s agenda.

UN Secretary-General’s Special Adviser on Climate Action and Just Transition Selwin Hart highlighted the potential for Chinese businesses and financial institutions to connect China’s clean-energy capabilities with growth opportunities across developing economies.

That argument points to one of the defining challenges of the energy transition: technologies such as renewable power, batteries and electrification are advancing, but deployment depends heavily on infrastructure, financing and access to markets.

Cross-border investment can help bridge those gaps.

The opportunity is not simply to export technology. It is to develop financing structures, local supply chains, skills and infrastructure that allow clean-energy systems to operate sustainably in emerging markets.

This makes sustainable finance a critical component of the infrastructure equation.

Sustainable Finance Needs Investable Projects

For institutional investors, the existence of a sustainability goal is not enough to make an infrastructure project financeable.

Projects need predictable revenue models, credible governance, appropriate risk allocation, technical feasibility and measurable outcomes.

The summit’s emphasis on private-sector-led partnerships suggests an effort to connect sustainability objectives with projects that can attract commercial participation.

Green mining, sustainable transport, biodiversity conservation and ocean protection, for example, require capital-intensive infrastructure but often involve complex revenue models and long investment horizons.

Financial innovation can potentially help bridge the gap.

Blended finance, sustainability-linked structures, climate funds and other mechanisms can reduce risks or improve the investment profile of projects that generate significant public benefits.

For the financial sector, this turns SDG infrastructure into both a development challenge and an opportunity to build new investment products.

Transport Safety Enters the Sustainability Conversation

The summit also placed road safety within the broader infrastructure agenda.

UN Secretary-General’s Special Envoy for Road Safety Jean Todt noted that 2026 begins the UN Decade of Sustainable Transport, arguing that the scale of Belt and Road connectivity needs to be matched by an equally strong commitment to safety.

That is an important expansion of the sustainability conversation.

Transport infrastructure can reduce travel times and improve trade, but its benefits are weakened if road design, vehicle standards, public transport systems and safety technology fail to keep pace.

Connected transport systems could increasingly combine physical infrastructure with digital monitoring, intelligent traffic management and data-driven safety measures.

Regional Cooperation Becomes the Delivery Mechanism

Several UN officials emphasized the importance of collaboration between governments, international organizations, financial institutions and private companies.

Sanda Ojiambo, UN Assistant Secretary-General and CEO of the UN Global Compact, described resilient infrastructure as a foundation for long-term sustainable development and pointed to the new expert groups and guidance initiatives as examples of cross-border collaboration.

UN Under-Secretary-General for Economic and Social Affairs Li Junhua similarly emphasized that no single country can address complex connectivity challenges independently.

That message is particularly relevant as infrastructure systems become more interconnected.

A renewable-energy project can depend on international financing and equipment supply chains. A digital infrastructure project can involve technology providers and data flows across several jurisdictions. Sustainable transport corridors can require coordination among neighboring governments.

The business case therefore increasingly depends on ecosystem coordination.

Singapore and ASEAN as a Regional Connector

The summit also highlighted the role of Singapore and ASEAN in connecting investment, technology and sustainability initiatives across Asia.

UNESCAP Executive Secretary Armida Salsiah Alisjahbana, along with UN resident coordinators Stephen Jackson and Nikolas Myint, emphasized the importance of cross-border cooperation and the contribution of China, Singapore and ASEAN to regional stability and progress toward the SDGs.

For Singapore, the summit reinforces its position as a financial, logistics and technology hub linking Asian markets.

For businesses, the broader significance is the emergence of infrastructure investment as a multidisciplinary market spanning finance, technology, energy, transportation and sustainability.

From Commitments to Measurable Outcomes

The most important question following the summit is implementation.

Declarations and expert groups can establish priorities, but achieving the SDGs requires projects that move from discussion to financing, construction and measurable impact.

The 12 initiatives launched at the summit provide a framework for doing that across areas ranging from green minerals and electricity emissions standards to biodiversity, transport and financial inclusion.

The next phase will depend on whether these initiatives generate investable projects, scalable technologies, common standards and partnerships that can operate across borders.

That is ultimately what the summit’s “Connect for Better World” theme represents: not connectivity as an end in itself, but as infrastructure through which capital, technology and expertise can be combined to address development challenges.

For investors and companies, the opportunity lies in turning that ambition into commercially viable and measurable infrastructure solutions.

Market Landscape

Sustainable infrastructure is becoming a convergence point for green finance, digital infrastructure, AI governance, energy transition and cross-border investment.

The competitive environment includes multilateral development banks, sovereign investors, infrastructure funds, commercial banks, technology providers and major engineering companies.

Three developments are particularly important:

• Digital infrastructure is becoming core infrastructure, increasing demand for sustainable data centers, connectivity and responsible AI systems.
• Climate investment is moving toward bankable projects, increasing the importance of project preparation, blended finance and measurable outcomes.
• Supply-chain resilience is becoming an infrastructure priority, linking transportation, energy, technology and manufacturing investments.

The challenge is execution. Large infrastructure initiatives require long-term capital, regulatory coordination and credible mechanisms for measuring environmental and social outcomes.
