* S.Korea auto group says subsidies aiding China EV sales
* Auto lobby group optimistic about Trump tariff decision

SEOUL, May 3 (Reuters) - A South Korean automakers' group called on Friday for an end to generous state subsidies for sales of Chinese electric vehicles (EVs), citing a potential threat to local automakers and Beijing's "discrimination" against EVs equipped with Korean batteries.
Jeong Marn-ki, president of the Korea Automobile Manufacturers Association, said Chinese automakers could boost EV exports as domestic demand suffered from a phasing out of Beijing's EV subsidies and a trade dispute with the United States.
"Chinese automakers, which are undergoing difficulties at home, are expected to turn their eyes into the neighboring Korean market," Jeong told Reuters in an interview.
South Korea - home to Hyundai Motor and Kia Motors - offers one of the world's highest subsidies for electric cars, industry officials say.
Chinese carmakers including BYD, accounted for nearly 40 percent of the 19.3 billion won ($16.5 million) in Korean EV subsides provided to imported carmakers last year, according to industry data.
However, while Chinese automakers are boosting EV sales in Korea, EVs equipped with Korean batteries are not eligible for state subsidies in China.
"China has created an uneven playing field for foreign brands," said Jeong, who heads the lobby group which represents Hyundai, Kia and other domestic automakers.
"International relations should be based on reciprocal principles. If Beijing wields a knife, we should wield a knife too."
Chinese carmakers are narrowing the gap with Hyundai in the sale in South Korea of electric buses, which are eligible for subsides of 100 million won ($85,500) each, according to industry data.
Chinese automakers like BAIC are now looking at expanding into the passenger electric car segment in Korea, Jeong said.
"It is like South Korea is using taxpayers' money to nurture China's EV industry."
Jeong also said he was hopeful that the United States would exempt South Korea from potential vehicle tariffs, given that Seoul made concessions on autos in a revised trade deal with Washington.
U.S. President Donald Trump has threatened to levy tariffs of some 25 percent on imported vehicles and auto parts on national security grounds.
"I am optimistic about the decision. But who knows? Trump is unpredictable," Jeong said. ($1 = 1,169.9000 won) (Reporting by Hyunjoo Jin; Editing by Richard Pullin)
