Indonesia, which built new sporting facilities in 2011 for the Southeast Asian Games, has been seen as a favourite since Vietnam announced last month that it was withdrawing as host for financial reasons.
"I don't think other competitors can offer better conditions than Indonesia for the time being," Olympic Council of Asia (OCA) honorary life vice-president Wei Jizhong told AFP during a five-day visit to assess whether the country's facilities would be up to hosting the Games, the world's second biggest multi-sport event after the Olympics.
A source from the Indonesian Olympics Committee (KOI) told AFP that Malaysia and Singapore had offered to jointly host the event and that Qatar had also made a bid.
Wei said Indonesia was well-equipped as it would be able to renovate existing facilities, rather than starting construction from scratch, in the short amount of time available.

"I think they can do it within two years," he said as he inspected an exhibition centre in Jakarta which he said could host up to seven sports.
The city's cavernous Gelora Bung Karno sports complex -- whose main stadium seats more than 80,000 people -- would likely be the central venue.
Indonesian officials had earlier indicated that the Games would likely take place in the country's second biggest city, Surabaya, but Wei said today that Jakarta would be the most suitable.
Wei yesterday visited the Jakabaring sport complex on Sumatra island, one of the main venues of 2011 Southeast Asian Games, and is scheduled to visit Bandung city in West Java on tomorrow to assess another venue.
