Thailand has successfully negotiated the first protocol amending the ASEAN-Hong Kong Investment Agreement (AHKIA), signed 20 September, opening investment markets in priority sectors—automotive, automotive components, and printed circuit boards. The deal enables Thai enterprises to tap regional supply chains and allows Thai investors to use Hong Kong as a gateway to China's Belt and Road Initiative. Key: new commitments do not require changes to domestic law or diminish state regulatory authority, making this a strategic win for SMEs seeking to upgrade manufacturing capabilities and international market access without regulatory friction.
