Businesses across the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) are accelerating their expansion into ASEAN region amid escalating global uncertainties and intensifying tariff pressures.
The ASEAN is made up of Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Viet Nam, with Timor‑Leste joining as the newest member in 2025.
A new joint study, “Hong Kong Empowers GBA Enterprises for ASEAN Growth Amid Global Trade Challenges”, released by UOB Hong Kong and the Hong Kong Trade Development Council (HKTDC), revealed that GBA companies are now scaling their ASEAN strategies with greater urgency to boost growth and strengthen supply chain resilience.
ASEAN growth set to accelerate further
Reflecting this renewed urgency, the study finds that 73% of GBA respondents intend to accelerate their business development in ASEAN, reinforcing the region’s importance as a long-standing and increasingly urgent growth engine amid global trade frictions.
ASEAN economies continue to gain prominence, with Singapore, Vietnam, Thailand, Malaysia and Indonesia emerging as the top destinations for GBA enterprises over the next three years.
To support expansion plans, companies expect to allocate an average of 30% additional resources to their ASEAN expansion plans. Vietnam is the top priority (47% increase in resources), followed by Indonesia (37%) and Thailand/Malaysia (32% each).
From a strategic perspective, the primary focus is on driving sales growth – especially in Thailand, Vietnam, and Indonesia – while expanding production and sourcing bases, with Vietnam, Thailand and Malaysia the top choices.
Even in Singapore, where GBA enterprises already have the largest footprint, respondents intend to commit an average of 23% in extra resources to accelerate their business development in the country, especially in areas, such as financing and establishing regional offices.
The study also reports a 25 percentage point year-on-year increase in the number of GBA businesses seeking to expand or maintain sales operations within the ASEAN bloc, with 98% of surveyed enterprises continuing to target these dynamic sales markets.
"This acceleration underscores the region's heightened urgency to navigate intensifying geopolitical and tariff pressures," the report said.
It added that 91% of respondents intend to expand or maintain their ASEAN-based production and sourcing hubs — a seven percentage point increase compared to 2024, highlighting stronger intent to diversify supply chains and mitigate external risks.
Heightened challenges in ASEAN expansion
While the momentum is clear, the study also highlights significant hurdles GBA enterprises face, as they expand into ASEAN. The most cited challenge is finding suitable local partners (47%), a figure that has risen by 24 percentage points since 2024 and has climbed steadily over the past three years.
Cultural and language barriers (46%) and difficulties in sourcing specialist talent (40%) are also on the rise, up 23 and 15 percentage points, respectively. These challenges underscore the need for trusted advisors and deeper cross-border support.
The study also reveals continued progress among GBA companies in pursuing sustainability goals. Of the participating enterprises, 83% currently have green initiatives underway, slightly up from 81%in 2024 and marking a three-year high.
Furthermore, 96% of respondents plan to increase or maintain their ESG funding over the next two years, with 66% intending to boost their ESG investment — a 26 percentage point jump from 40 percent in 2024, recording a three-year high.
For the next two years, the average intended level of ESG funding on the part of GBA enterprises is now HK$874,771, nearly double the HK$462,535 recorded in 2024.
Wing Chu, deputy director of HKTDC Research, said, "With the shifting global supply chain landscape and tariff uncertainties, many GBA enterprises are accelerating their ASEAN engagement not merely as a means of risk diversification, but to capture new growth opportunities in fast-evolving markets."
"Hong Kong's unique positioning as a superconnector allows businesses to leverage the city’s comprehensive trade, financial and professional services platform to navigate this transformation efficiently, while strengthening their ESG commitments. The HKTDC will continue to proactively support GBA enterprises in leveraging Hong Kong's professional services to capitalise on opportunities in the ASEAN markets."
Among the 73% of GBA enterprises intending to accelerate their ASEAN development, two-thirds have leveraged Hong Kong's platform to advance their expansion.
On the ESG front, Hong Kong offers diversified, forward-looking, sustainable development solutions necessary for green and sustainable business development, with its green services rated at 8.8 out of 10 by surveyed enterprises.
In addition, more than 90% of respondents are considering or already increasing their uptake of Hong Kong's sustainable development services over the next two years. The most in-demand services include: (1) green financial products and services; (2) green financing services; (3) ESG reporting, due diligence, ESG rating; and (4) green asset valuation.
The report, based on insights from more than 600 businesses across Hong Kong and five key mainland GBA cities (Dongguan, Foshan, Guangzhou, Shenzhen and Zhongshan), examines how businesses are adjusting strategies amid global challenges, and how Hong Kong plays a pivotal role as a superconnector, empowering GBA enterprises to diversify supply chains within ASEAN and advance their ESG commitments.
