Western Asia is part of MENA-area. Northern Asia is part of Russia and goes with European region. South Asia will be it's own region. East and SouthEast Asia will be a joined region. Central Asia can be a region on it's own.
Western Asia is covered under the debate of Africa / Western Asia (Middle East).
Central Asia should be an underrepresented area because there are no prides and due to existing laws, political and religious climate it is not foreseen prides will start happening soon. See debate about unrepresented areas.
In South Asia (India and Nepal) we do have some prides. Pride movement in India is developing. The geographical size is big, but the language shared.
In East Asia there are pride in China near the coast-line. This makes the geographical area together with SouthEast Asia workable.
Combining East and SouthEast Asia is combining strong cultural, political, lingual and legal differences that will complicate collaboration in this one region massively.
