for my paper i have to write (on a political science topic) i was wondering if theres such a thing as the?

politics of travel?

i guess what im getting at is does traveling to other countries increase understanding but how can i bring that under the topic of politics? i was thinking something along the lines of is globalization bad or something about travel writing. would kind of question should i pose though because i know this 'travel topic' is stretching it but my major is politics and it has to be somehow 'political' in nature.

in other words how can i get away with talking about people traveling to other countries, maybe also include something about culture, and have it come off as politically based paper

sorry if it doesnt make sense

by the way this is for a very extensive paper.
