South Korea hopes a high-level visit to Tokyo next week will kickstart talks aimed at a breakthrough in historical disputes despite concerns the death of former Japanese premier Shinzo Abe could change Japan's policy priorities, Seoul officials said.

Relations between the two North Asian U.S. allies have been strained over disputes dating to Japan's 1910-1945 occupation of Korea. Washington has been pressing Tokyo and Seoul to mend fences in the face of the North Korean nuclear threat and the rising influence of China.

Officials in the administration of South Korean President Yoon Suk-yeol, who took office in May vowing to improve ties with Japan, told Reuters they feel emboldened by Japanese Prime Minister Fumio Kishida's election victory which could give him more scope to advance his policy agenda for another three years.

Foreign Minister Park Jin will visit Japan on July 18-20, the ministry said, a trip which a senior official handling Japan policy said is aimed at "turning on the tap" for serious negotiations on issues relating to forced labour, which stalled under Yoon's predecessor.

Park will meet his Japanese counterpart Yoshimasa Hayashi and discuss relations between the two countries and issues on the Korean Peninsula, the South Korean ministry said. Park will also pay respects to Abe.

Another South Korean official said Yoon would send a high-level delegation led by the prime minister when Japan holds a public memorial service for Abe, who was shot and killed last week while on the campaign trail.

Yoon would also likely use his Aug. 15 Liberation Day speech marking Korea's independence from Japan as a chance to send a reconciliatory message to Tokyo, the official added.

"What we're trying to do is to open the door for real talks," the senior official said.

The assassination of Abe, who was a defining leader in Japanese politics and a divisive figure in Korea, has raised new doubts about the outlook for relations with South Korea, where bitter wartime memories run deep.

Some analysts say Korea might be put on the back burner while Kishida presses to achieve Abe's unrealised dreams, including constitutional reform aimed at allowing Japanese troops to fight overseas.

But some Korean officials see Japan as more willing to talk now, with pressure by U.S. President Joe Biden's administration also playing a potential role.

"We see great potential in stronger trilateral relationships," Derek Chollet, Counsellor of the U.S. State Department, told Reuters this week.

COOPERATION 'INEVITABLE'

Japan's chief cabinet secretary, Hirokazu Matsuno, said on Friday that cooperation with Seoul and Washington was "inevitable" for responding to North Korea's threat and other regional issues.

"Although relations between Japan and South Korea are in a very severe state ... we don't think it can be left as it is," he told a news conference, adding Tokyo would work together to resolve history issues and restore ties.

Yoon and Kishida met Biden on the sidelines of last month's NATO summit for their first trilateral talks, and Chollet said Washington stands ready to facilitate strong ties between its two allies.

At home, the Yoon government is gathering opinions from victims of forced labour, lawyers and experts via a newly launched public-private panel, which held its second hearing on Thursday.

At stake are South Korean court orders for a seizure of assets of Japanese companies accused of not compensating some of their colonial-era labourers. Tokyo has warned of serious repercussions if the orders are enforced.

The first official said the Yoon administration was seeking a "realistic, feasible proposal" that can win consent from both victims and the Japanese government.

A third official was more cautious, saying the compensation issue should be resolved alongside trade and other rows, which could make a compromise more difficult.

Yuko Nakano, a fellow at the U.S.-based Center for Strategic and International Studies, said any compromise would require patience and commitment from both Yoon and Kishida.

"High-level visits and meetings often attract attention, but equally important is to continue building on efforts that are happening below the surface," she said.
