South Korean Government Subsidizing the Sale of Chinese Made Electric Buses

I read this article and it left me wondering why is the Korean government subsidizing Chinese electric buses and not domestically made ones?:

Concerns have grown over electric buses made in China, which are set to hit the Korean roads within a few months, taking advantage of the handsome subsidy given by the Korean government.

Industry officials point out the government policy may allow Chinese companies to take the lead in the Korean electric vehicle and battery markets, given that the buses are equipped with batteries made in China, the country which has remained reluctant to subsidize batteries produced by Korean companies.

According to industry officials, Wednesday, the Ministry of Environment decided last month to subsidize the eBus-12 made by BYD, China’s largest electric vehicle maker.

The 11-meter-long low-floor bus is powered by a 324-kilowatt-hour lithium-ion battery pack also made by BYD.

The subsidized bus is attracting clients with a more competitive price.

Because the environment ministry, the land ministry and local governments are giving subsidies to the bus maker, the subsidized bus costs 200 million won ($179,000) less than it would without the subsidies.  [Korea Times]

You can read more at the link, but the Chinese government is not subsidizing Korean made buses in China. So is the ROK government subsidizing these buses as part of some larger deal perhaps to get China to withdraw some of is economic sanctions caused by the phony THAAD controversy?
