Just few points from my experiences...

- to have an interest in foreigners
- to start talking to them
- to ask questions to them (but not too personal ones)
- to be honest to them
- to have your own opinions
- to be charming and funny

From my experiences, I feel that people are more open-minded for strangers when they are on a trip, so don’t be shy to talk to someone sitting next to you on a flight or someone you meet at an airport.

There is one Japanese saying “一期一会 ichigo-ichie”, which means that every encounters is unique, or one chance in a lifetime. You should enjoy once-in-your-life encounters.

One more thing, when I’d like to make a good relationship with foreigners, I stop judging them by looks, nationalities, ages and try to see what they are.
