THE GOVERNMENT’S “Thailand 4.0” development drive is seen as providing a potential windfall for Phnom Penh Special Economic Zone Plc , whose industrial-estate operators hope manufacturers from Thailand and other countries with production at the Industry 1.0 or Industry 2.0 stage will shift their operations to Cambodia’s economic zones. PPSEZ, which was founded in 2006, runs two industrial estates one in the capital and the other in the Poipet Special Economic Zone.
