I'm not completely following the logic (could be due to not enough coffee yet); but if you want to target multiple countries with different ads & keywords; then you can create a new campaign for each country and use the ads/keywords appropriate to each country in that campaign.
If you are just looking for people who are not located in your area, but are searching with geographic words; you can also set the advanced location targeting to only those looking for info on your area; but are not physically located there (or vice versa) in the advanced location targeting options.

hat I prefer to do is use just phrase match and then over time build up a negative keyword list of all the keywords that come through that are obviously untargeted
