"At the upcoming summit, the two leaders are expected to discuss specific ways to strengthen the countries' special strategic partnership," the presidential office Cheong Wa Dae said earlier.

The leaders are also expected to discuss joint efforts to promote regional cooperation at the meeting at Cheong Wa Dae.

Moon unveiled his so-called New Southern Policy during his trip to Indonesia last year, under which he seeks to greatly improve his country's diplomatic and economic ties with Southeast Asian countries, such as India and all 10 members of the Association of Southeast Asian Nations that include Indonesia.

The South Korean president has vowed efforts to nearly double his country's trade with ASEAN countries to $200 billion by 2020.

With Widodo's visit, Indonesia has become the first ASEAN nation to have exchanged visits by their leaders with South Korea since Moon took office in May 2017, Cheong Wa Dae said. (Yonhap)
