Prehaps if you chaps didn't keep getting arrested in foreign countries for drug trafficking and stopped overstaying your visas you would be more welcome.
Prehaps if you stopped the internet, mail and credit card fraud your reputations would improve.
Prehaps if you improved your law and order situation and removed corrupt officials people would be easier about doing business with you.
Just suggestions of course, but somethings you have to do yourselves.
