The Belt and Road Initiative is accelerating and changing

Mainland China’s emergence as a major global investor is well recognised. In 2024, its total outbound direct investment (ODI) reached USD163bn, the fourth largest source of foreign direct investment in the world. Despite this, mainland China’s ODI flows are still small relative to the size of its economy, but we think they are set to accelerate. Tariff uncertainties could be a catalyst, with production moving closer to end-consumers. Domestically, “involutionary” competition has also incentivised more manufacturers to expand their footprint overseas.

A growing feature of mainland China’s ODI is that a rising share of investments are destined for BRI participating economies. The share of total mainland Chinese investments going to the BRI has risen steadily to 25% in the first six months of 2025, up from the average of 16% in 2021 and 2022. During the same period, the number of BRI participating economies also grew by 12 to 150 (out of a total of 195 nations in the world), representing over 70% of the world’s population. This reflects the significance of the BRI in mainland China’s growing investment network.

As the BRI enters its second decade, it will continue to be an important vehicle for mainland China’s overseas investment. However, it has also undergone a significant strategic evolution, transforming from a broad infrastructure-focused programme into a sophisticated framework deeply integrated with mainland China’s broader goals of global economic integration, supply chain resilience, and technological advancement. This shift is characterised by a strategic pivot towards “small and beautiful” projects that are green, digital, aligned with global chain dynamics, and concentrated on key regions, such as ASEAN and the Middle East. Mainland China is also leveraging multilateral trade frameworks, such as the Regional Comprehensive Economic Partnership (RCEP), to promote BRI direct investment.

The accelerating trade and investment connections under the BRI have also catalysed a structural surge in cross-border RMB demand. This is further facilitated by institutionalised mechanisms, such as bilateral currency swap agreements, and the expansion of RMB denominated trade settlement. As of May 2025, there are 32 bilateral currency swap agreements between the People’s Bank of China (PBoC) and other central banks and monetary authorities, among which 22 have BRI agreements with mainland China (PBoC, 10 June 2025).

Hong Kong is also poised to benefit from its unique position as a regional green and sustainable finance hub and the largest offshore RMB centre. As mainland China accelerates green transitions at home as well as in BRI economies, Hong Kong has ample opportunities to leverage its advantages in green finance. The city also has room to play an enhanced super connector role and facilitate broader use of the RMB internationally, such as in BRI economies, as well as creating venues for foreign investors to access an increasingly mature capital market with various options of RMB-denominated assets and risk management tools.
