Three leading Chinese automakers, MG, BYD, and Great Wall Motor (GWM), have established large-scale manufacturing facilities in Thailand and are planning to expand their production capacity.

MG's plant in Chonburi province has a maximum annual production capacity of 100,000 units, while GWM's Rayong factory can produce up to 80,000 vehicles annually.

BYD plans to scale up to 150,000 units per year.

The companies are not currently operating at full capacity.

BYD confirmed its expansion plans, aiming to reach full capacity within two years from the factory's Q3 2024 launch.

The company will begin exporting its first model, the BYD SEALION 6 DM-i, this year.

BYD Auto (Thailand) Co Ltd manufactures the BYD DOLPHIN, BYD ATTO 3, and the plug-in hybrid BYD SEALION 6 DM-i, with capabilities to produce both left- and right-hand drive vehicles.

SAIC Motor–CP's Chonburi plant produces models like the MG5, MG ZS (1.5L engine), and MG HS PHEV, exporting to Vietnam and Indonesia, with plans to expand to Malaysia this year.

The company invested heavily in developing the New Energy Industrial Park to support EV growth.

GWM announced plans to increase production at its Rayong factory in Q2 this year to meet domestic demand and expand global exports.

The company currently exports vehicles to Malaysia, Indonesia, Vietnam, Brazil, Australia, and New Zealand.

The Rayong plant supports a maximum output of 80,000 vehicles annually and employs over 1,100 people.

Local parts make up 45–50% of components used.

The companies are committed to continued investment in Thailand as a global manufacturing and export hub.
