Anwar said Thaksin's role during his leadership of the Association of Southeast Asian Nations will be in an informal capacity, alongside advisors from several of the bloc's 10 member states.

Anwar made the announcement during a visit to Malaysia by Prime Minister Paetongtarn Shinawatra. "Thank you for agreeing to this because we need the benefit of the experience of such a statesman," Anwar said of Thaksin during a joint press conference with Paetongtarn.

As planned, Malaysia will officially assume the role of ASEAN Chair on January 1, 2025, with the theme of inclusion and sustainability, reflecting Malaysia's desire to promote a unified and prosperous ASEAN.
