Imagine you are from a stereotyped country, as the president or a minister how would you improve this perspective of your country?

I think there are 2 Major workable actions; firstly, hire a Public Relations Firm and tell them what is needed to get across; meanwhile, those things that caused the idea of these "unfortunate stereotypes" should be quickly addressed; just how would depend on if the stereotype was real, or if the people who actually live their consider it a problem.
