The new chapters will provide greater support to its 4,300 members around the world.
It is understood that the RIBA hopes to foster better links with UK firms and local architects working in the various countries.
Singapore will be the first to open later this year and will be followed by the Hong Kong and Dubai-based chapters in 2009.
RIBA chief executive Richard Hastilow said: 'The development of these new chapters should have a two-way benefit – providing better support to our members living and working around the world, but also learning from their experience to inform the RIBA’s contribution to major international issues such as climate change and the growth of cities.
‘For this next step, we are focusing on countries where we have a significant core of members and good links with the national institutes and other strong partners.’
