South Korea's Industry Minister Kim Jung-kwan on Sunday said the U.S. is unlikely to slap higher tariffs on South Korea should the Korean parliament move swiftly to implement investment legislation sought by the U.S. next week as scheduled. Seoul has been in talks with Washington after U.S. President Donald Trump threatened to hike tariffs on goods imported from South Korea to 25%, blaming a delay in the Asian ally's enactment of commitments to invest $350 billion in the U.S. as agreed in a trade deal last year.
