Japan said yesterday it does not plan to retract or renegotiate its stricter controls on high-tech exports to South Korea, a day after the South Korean president urged that the issue be resolved through diplomacy.
Tokyo tightened the approval process for Japanese shipments of photoresists and other sensitive materials to South Korean companies last week.
Japanese officials say such materials can be exported only to trustworthy trading partners, hinting at security risks without citing specific cases. They have rejected suggestions that the move was driven by a worsening in ties between the two countries related to historical issues.
“The measure is not a subject for consultation and we have no intention of withdrawing it either,” Chief Cabinet Secretary Yoshihide Suga said at a news conference.
He was responding to South Korean President Moon Jae-in’s appeal for a diplomatic solution thorough “sincere” bilateral discussions, urging Tokyo to withdraw what he described as a politically motivated measure.
Moon said Monday his country would be forced to take countermeasures if the restrictions on materials used mainly in semiconductors and displays cause damage to South Korean companies. The trade curbs have raised concern over possible disruptions for South Korean manufacturers and global supply chains, he said.
South Korea’s Trade Ministry says Seoul plans to file a complaint with the World Trade Organization.
Japan’s trade measures followed recent South Korean court rulings ordering Japanese companies to compensate South Korean plaintiffs for forced labor during World War II.
The export restrictions cover fluorinated polyimides, which are used in organic light-emitting diode (OLED) screens for TVs and smartphones, and photoresist and hydrogen fluoride, used for making semiconductors.
Japanese officials say those chemicals are sensitive materials that could be used in fighter jets, radars and chemical weapons. They say the decision to tighten export controls was based on a lack of trust that posed a risk to national security.
They haven’t elaborated on the alleged security risks, but Japanese Prime Minister Shinzo Abe and his ultra-conservative aides have hinted there may have been illegal transfers of sensitive materials from South Korea to North Korea.
“South Korea says it is adequately abiding by the sanctions and that it is properly carrying out export controls. But South Korea, with its handling of the former Korean wartime laborers issues, clearly demonstrated that it is a country that does not keep promises. Naturally, we have to assume it also fails to keep promises on export controls,” Abe said Sunday on a Fuji Television talk show.
On another Fuji talk show last week, Koichi Hagiuda, a senior lawmaker in Abe’s Liberal Democratic Party, said some chemical exports were unaccounted for. A day later, former defense minister Itsunori Onodera mentioned a South Korean newspaper report in May about illegal shipments of sensitive materials that could have ended up in North Korea and Iran via third countries. It did not cite any sources.
South Korea denied the allegations, summoning a Japanese embassy official to protest Abe’s suggestion that it could not be trusted to faithfully implement sanctions against North Korea, Foreign Ministry spokesman Kim In-chul said yesterday.
South Korean officials say there is no evidence to back up such claims and that Seoul has been properly implementing international sanctions against the North over its nuclear weapons program.
Sung Yun-mo, South Korea’s Minister of Trade, Industry and Energy, said yesterday that an “emergency inspection” of companies that process and export the chemicals imported from Japan found no sign of illegal transactions allowing them to reach North Korea or any other country affected by United Nations sanctions. He said only Japan had questioned the credibility of South Korean export controls. Mari Yamaguchi & Kim Tong-Hyung, Tokyo , AP
