My average brain power cannot compute - How can Saudi Arabia & UAE be on the list, along with UAE & Oman... But not Saudi Arabia & Oman?

since its gdp per capita, uae+saudi & uae+oman are both greater than saudi+oman A+B & A+C are greater than B+C... quite logic, isnt it?

Oman ranks at 32, Saudi Arabia at 14 and UAE at 8.

UAE + SA = 22 (11 avg)
UAE + O = 40 (20 avg)
SA + O = 46 (23 avg)

So because UAE > SA, then the third combination doesn't quite make the cut.

I think you meant UAE < SA

Well I meant UAE had a greater GDP per capita, rather than the actual rank. But yes, in rank terms, UAE < SA as 8 < 14.

A few countries that are close, but do not share a border: Singapore-Brunei: 5.5; Singapore-Malaysia: 26 (Brunei and Malaysia do border each other and score 26.5); Australia-New Zealand: 26.5; Japan-South Korea: 32. You can see why Singapore (5) and Brunei (6) didn't want to be part of Malaysia (47).

Actually, Singapore did not secede from Malaysia; Malaysia expelled Singapore. Due in part to the anti-Chinese sentiments that led to anti-Chinese riots in Kuala Lumpur several years later.

How did I not get USA-Canada?!! *facepalm* Also are we Including the French Guiana border, or is that just not very rich countries per capita. Also assuming you don't include the dubious Qatar-UAE border. Kuwait Kind of surprised me and so did not seeing Sweden-Finland, guess that is for the same reason there is no Saudi Arabia-Oman, because Norway is like UAE, it is the largest out of those three

Denmark is 22nd and Germany is 21st, so their average is only 21.5, this not making the list. Germany only makes it on here elsewhere as it borders richer countries.
