On October 11, 2022, Chaipak Siriwat, the Vice President of the National Olympic Committee of Thailand (NOCT), revealed the framework for the bidding process for the 2025 SEA Games.

He emphasized that the host cities or provinces should aim to organize the Games at a budget-friendly cost and that there would be no requirement to build new venues.

[1] In October 2022, Prachum Boontiem, the Vice Governor of the Sports Authority of Thailand (SAT), nominated eight bidding parties from twelve cities or provinces interested in hosting the 2025 SEA Games.

The city Bangkok as well as the provinces of Chiang Mai, Nakhon Ratchasima, and Songkhla submitted sole bids, while Bangkok, Chonburi, Songkhla, Krabi, Phuket, Trat, Amnat Charoen, Sisaket, Ubon Ratchathani, and Yasothon were proposed as potential bidding provinces.

[17] The event also featured renowned athletes, including Vareeraya Sukasem, an Olympic skateboarder, and Saysunee Jana, a five-time Paralympic gold medalist in wheelchair fencing.

Additionally, several celebrities joined the occasion, such as Matthew Deane, Khemanit Jamikorn, James Fagerlund, and Nakorn Silachai.

The games aim to achieve net-zero emissions by promoting eco-friendly transportation, utilizing sustainable products, and selecting venues that prioritize environmental protection.

[19][20] This environmentally friendly vision will also be implemented in the 2025 FIVB Women's Volleyball World Championship, scheduled for August earlier in the year.

Since its debut in 2003, Timor-Leste will participate for the first time as a full ASEAN member state, with its official access to the association expected in 2025.

[37][38] The official awarding ceremony took place at the Chaloem Phrakiat Building at the Hua Mak Sports Complex in Bangkok on 23 November 2023.

[39][40] The official emblem for the 2025 ASEAN Para Games, designed by Adisak Muangkhong, was chosen through a nationwide contest.

The official motto for the 2025 ASEAN Para Games, Create Pride Together (Thai: สร้างความภูมิใจไปด้วยกัน, RTGS: Sang Khwam Phumchai Pi Duaikan, pronounced [sâːŋ kʰwāːm pʰūːm.tɕāj pāj dûaj.kān]), designed by Thawan Ditsathutham.
