I will tell you what my experience has been, when ever I drove to the part of the town where Indians live, some Korean I know loved to watch the Indians like some strange beings and laugh uncontrollably. Now being from similar ethnic group I asked why this making fun, the reply was that they just look funny. Go figure. Incidentally Pakistani's in general did not look funny to this Korean.
Secondly, I asked about what Koreans specially the one's in the US think about Indians (note Indians in the US are the highest income immigrant groups, mostly educated ones). There is a forum for Korean expats called missyusa.com and the consensus there is that these funny and strange looking Indians are the most arrogant pieces of work people could encounter and high GDP and proud Koreans could not figure out why these funny looking Indians from one of the poorest countries could be like that. Some were guessing that they are from a big country and have dreams of becoming a super power someday, so that probably explained this anomalous behavior. Others were guessing that because some of them are brahmins and high caste and are used to feeling superior over other people in their country, they are projecting this "funny" behavior to the rest of the world.
And of course there were anecdotes of occasional Korean solo girl tourists visiting India, getting proposed right and left by random Indian strangers, boasting that they are brahmins, as if it should mean something to a Korean.
Sorry for going OT, but could not help but provide some food for thought for our Korean, as he is an expert on Koreans and is a Korean, so he could add these tid-bits to his expert knowledge.
