It's quite rare to see a romantic coupling between East and South Asians, e.g. Chinese/Indian couples, especially between South Asian women and East Asian men. Such seems to be the case particularly in the West, like USA and UK. Could you think of the reasons why? Do Indian/Pakistani/Sri Lankan women not find East Asian men attractive enough to date or marry, compared to other non-South Asian men?

Well thats interesting question.

I will not comment, rather will wait for girls to say something. Though I can guess but lets see what ever I guessed is correct or not !

May be they didnt have tried to start a new relation. They just came and went maybe !

People must like to live here in india, then they wil like indians, start a new relationship, then the relationships bloom.

So initially the first few things are missing. Either they didnt like present india, or they didnt make good relationships.

He himself is a East Asian and he is asking Indian women that what is the reason according to them that east asian men and south asian women couples are hard to find !

in the west there are more of south/east asian people.. so theyve been mingling with these people for long.. as a result there are mre chances for attraction..
as for indian females or males for that matter, w eare exposed mainly to either indian or paki or of the like people.. we dont really get a chance to mingle with chinese or of the sort.. n where there are rare cases like these, couples do form..
its not anything like south asian girls dont find east asian men Attractive.. its just a matter of mindset of the subcontintent's females.. about having someone from their own culture..

fully agreed wid sanya.
