Mahidol University has maintained its lead among higher tertiary institutions in Thailand, according to a respected survey, but it still lags behind universities in Singapore and Malaysia.
Mahidol University's position remained unchanged as it was still in the group of universities ranked between 501-600 in this year's Times Higher Education World University Rankings.
Chulalongkorn University, King Mongkut's University of Technology Thonburi and Surananee University of Technology were also in the same positions in the grouping between 601-800.
Chiang Mai University was dropped to a lower tier below 800, joined by Kasetsart University, King Mongkut's Institute of Technology Ladkrabang, Khon Kaen University, Prince of Songkhla University and newcomer King Mongkut's University of Technology North Bangkok.
The survey does not give specific positions for lower-ranking universities, but puts them in groups.
The rankings list 1,000 universities around the globe each year. The rankings measure quality of teaching, research, citations, international outlook and industry income.
The highest-ranked institution in Southeast Asia was National University of Singapore (NUS), at 22nd, and Nanyang Technological University, also in Singapore, at 52nd.
The University of Malaya in Malaysia fared better than Thai peers as it was scored among the top 400.
NUS was also rated the best university in Asia, followed by Peking University at 27th and Tsinghua University in Beijing at 30th.
The three Asian universities made it into this year's top-30 schools for the first time.
Oxford University once again topped the annual rankings, now in their 14th year, with the University of Cambridge in second place for the first time. The California Institute of Technology and Stanford University were joint third.
Phil Baty, editorial director for global rankings at Times Higher Education, said in a statement, "The rise of China in this year's table is remarkable and demonstrates the way the global higher education landscape is changing." He noted two Chinese schools were listed in the top-30 representatives for the first time.
"East Asian countries outside of China will need to work hard to stay stable as its neighbour soars to join the global elite," Mr Baty said.
