South Korea has been calling on Japan to retract the measure and hold talks to resolve the frictions, but Japan has remained tight-lipped over the request.

South Korean officials also refuted claims that Tokyo has provided a full explanation or that it gave prior notification before implementing the restriction.

"It is not true that the South Korean government has agreed to Japan's stance that yesterday's meeting was a mere explanation," the official said.

Seoul has also demanded that Japan provide acceptable evidence or grounds for questioning its export control system, the official added.

The trade ministry official refuted Japan's claim that South Korea had not requested additional discussions in the future.

"We have repeatedly proposed another round of talks over the tech trade restrictions before July 24," the official said, adding that the Japanese side did not clearly state whether it would accept the proposal.

The office of President Moon Jae-in, meanwhile, is poised to take stronger actions against Tokyo, an official said.

"It looks like Japan is poised to take the trade row between the neighbors longer than expected," said a Cheong Wa Dae official who asked not to be named. "Our attitude is that we are determined for the current situation." (Yonhap)
