SEOUL 鈥 South Korean President Lee Jae Myung is set for a summit with Japanese Prime Minister Sanae Takaichi on Tuesday, a week after one with Chinese President Xi Jinping, as Seoul seeks to balance ties with both neighbors.

The summit in Japan鈥檚 Nara City comes amid a growing diplomatic dispute between Beijing and Tokyo, and analysts expect Ms. Takaichi to highlight the stability of three-way ties between the United States, Japan, and South Korea.

Mr. Lee has taken an approach of 鈥減ragmatic diplomacy鈥 in seeking to balance ties with China and Japan, which could making it easier to reach pacts in business fields such as artificial intelligence (AI).

鈥淗istorically, disputes between China and Japan go on for a long time,鈥 said Yang Kee-ho, a Japanese studies professor at South Korea鈥檚 Sungkonghoe University.

鈥淚t is very likely that the Sino-Japanese relationship will deteriorate throughout (Takaichi鈥檚) term in office.鈥

Beijing was infuriated after Ms. Takaichi said in November a Chinese attack on democratically governed Taiwan could be deemed an existential threat to Japan, which could trigger a military response from Tokyo.

China regards Taiwan as part of its territory, a claim the island鈥檚 government rejects.

In the face of the tension with China, Japan may seek to bolster diplomatic ties with South Korea, possibly through a strategic partnership, said Lee Chang-min, another Japan聽expert at Hankuk University of Foreign Studies.

鈥淣ot only has Japan鈥檚 relationship with China deteriorated, the United States has also put a little distance from Japan in its (Taiwan) stance,鈥 said Mr. Lee.

South Korea鈥檚 Mr. Lee and Ms. Takaichi may discuss the Japan-China dispute during their meeting, a security adviser to Lee, Wi Sung-lac said on Friday. However, South Korea is unlikely to take sides, analysts said.

鈥淥ur relationship with Japan is as important as our relationship with China,鈥 Mr. Lee told reporters during his state visit to China last week.

NORTH KOREA ISSUES
Perennial concerns, such as the denuclearization of the Korean peninsula and the fate of Japanese nationals abducted by neighboring North Korea are also expected to figure on the agenda.

However, analysts said the areas offering the easiest scope for concrete agreements may lie in business, such as cooperation in artificial intelligence and chips, and easing travel for business executives between the countries.

The two leaders are expected to extensively discuss 鈥渁reas directly related to people鈥檚 livelihoods … such as intellectual property and AI,鈥 Mr. Wi said.

The summit in Ms. Takaichi鈥檚 home prefecture of Nara also offers Mr. Lee an opportunity to take up issues of regional cooperation, as part of a pledge to spur development in areas outside Seoul.

Ties are still plagued by longstanding tension on topics such as Japan鈥檚 colonization of Korea, including the treatment of Korean women forced to work in its wartime military brothels.

Such historical issues have moved from the center stage of relations for now, analysts said, though some in South Korea still want them to stay high on the agenda.

Mr. Lee鈥檚 two-day visit to Japan, shorter than his four-day trip to China, is part of 鈥渟huttle diplomacy鈥 efforts that the two countries agreed last year.

Even if the trip has no tangible outcome, said Mr. Yang, 鈥淭he most important thing is to keep the shuttle meetings going … and eventually reaching concrete results.鈥 鈥 Reuters
