Countries On A Line With Equal Latitude and Longitude

Start at the point where the equator meets the prime meridian and proceed northeast along the line defined by all points where the degrees of latitude equals the degrees of longitude (ie, 5N, 5E). Name all countries in order that you pass through as you follow this line.

Then follow the antipodal path on the other side of the world that starts where the equator meets the 180 deg longitude line (for this path the latitude and longitude values will always add to 180 instead of being equal). Proceed northwest from this point and name all countries you pass through in order.
