I have just put down some random articles I have found, Im not quite sure what you wanted but I hoped I helped.
Americanisation is rather subtle. I think its mainly cultural influences from films and other mass exports combined with McDonald's and starbucks. Lots of countries feel that they are losing their own culture.
It is these mass exports combined with the american boastfulness that leads to a General dislike of Americans.
American pride can easily be misread as arrogance, we regularly hear Americans tell us they have the best country in the world etc.etc. and then being bombarded with Starbucks is like having you tell us "You must have this to be a good country like us."
You can see why this doesn't go down well.
