A senior official of South Korea's presidential office says the government will deal resolutely with Japan's stricter export restrictions against the country.

National Security Office chief Chung Eui-yong met with ruling party lawmakers on Tuesday to discuss the export curbs Japan launched on July 4 on key high-tech materials needed to make semiconductors.

Chung said it's a "very serious and reckless challenge that shakes the foundation of South Korea-Japan friendly relations," which have been arduously built up since the 1965 establishment of diplomatic ties.

He noted that South Korea will "respond resolutely until the Japanese government retracts the measure."

The ruling party said the meeting's attendees explored the intentions and background behind Japan's tougher restrictions. They concluded there are multiple factors, include past problems between the two countries, the threat posed by South Korea's economic rise and improved inter-Korean relations.

The attendees agreed to make every effort to prepare for all possible steps Japan may take, including additional measures. They also agreed to approach neighboring countries to bolster international cooperation.

South Korean President Moon Jae-in plans to meet with the leaders of five ruling and opposition parties on Thursday. He is apparently aiming to secure parliamentary support for his plan to provide funds to produce the key high-tech materials domestically.
