My twin brother wants me to date a Thai.

I have been dating a bunch of women since I travel a lot for business causes. I got interested with some but it fades easily as time goes by. I told my brother about it and he asked me to date Thai ladies. I don't know what has gotten into him. Since he went to Thailand once, he recommends Thais most of the time. Seriously, are Thai women open with dating foreign men? What are they like?
