Deputy Prime Minister and Commerce Minister Suphajee Suthumpun has announced the conclusion of negotiations on expanded investment market access under the ASEAN–Hong Kong, China Investment Agreement (AHKIA). Thailand coordinated the negotiations, leading to the signing of the agreement’s First Protocol during the 10th ASEAN Economic Ministers–Hong Kong, China Consultation in Manila on September 20.

The protocol adds market-access commitments intended to create more investment opportunities and provide clearer conditions for businesses. Thailand expects greater investment in industries such as automobiles, automotive components, and printed circuit boards, while developing closer supply-chain connections between Hong Kong investors and Thai companies.

Thai businesses will also gain broader opportunities to invest in Hong Kong, with potential access to the Chinese market through the Belt and Road Initiative. Thailand’s commitments are consistent with existing domestic laws and preserve the government’s authority to regulate and determine public policy.

AHKIA originally covered investment protection, promotion, and facilitation, while negotiations on market access began in 2021. Following legal review and verification completed in March 2026, the protocol expands the framework to provide greater transparency and predictability for investors while supporting technology, advanced industries, and regional supply chains.
