Bosch plans to invest EUR43m in Thailand to build a fuel-injection systems plant and related R&D facilities, according to local reports.

This is part of a previously reported EUR80m investment plan for southeast Asia this year which also involves new manufacturing and sales facilities in Indonesia, Philippines and Malaysia scheduled to become operational in 2017.

The new Thai facilities will be built in the Hemaraj Eastern Seaboard Industrial Estate in Rayong and are scheduled to become operational in mid-2017. The fuel injector plant will have an annual capacity of 1 million systems per year and will employ 800 people.

In Indonesia the company completed construction of its first plant in 2014, to make parts for Japanese automakers which are dominant in this market. The EUR10m facility makes oxygen sensors and fuel injection systems.

The company is increasing its exposure to South-east Asia's growing automotive industry, where it says around 3.9m vehicles were produced last year – led by Thailand and Indonesia.

It is targeting group revenues of EUR2bn in this region by 2020, up from EUR800m last year.
