Shortest route through all world capitals

Starting in Dublin, Ireland and first moving eastward, we are looking for the shortest route through all 196 world capitals, ending in Dublin. All capitals are to be visited once, except for Dublin, where you will both start and end.
Both the country and capital will be accepted. If a country has more than one capital, all will work, but only one will be displayed
The distance to the current unknown capital from the previoulsy guessed capital is given. If a country has more than one capital, the distances from the previous capital to all of its capitals will be given. The next hint is only the distance from the displayed capital to the next capital

There is at least one error in the quiz. The distance from Tokyo/Japan to Taipei/Taiwan is about 1330 miles and thus much shorter than to Palakir/Micronesia (2307 miles). Also Manila/Philippines (1749 miles) and Ngerulmund/Palau (1958 miles) are closer to Tokyo than Palakir.

There might be other errors, but I got stuck on this one...

Found 4 other errors.

- Mogadishu/Somalia (837) is closer to Victoria/Seychelles than Port Louis/Mauritus (1082)

- Dodoma/Tanzania (638) is closer to Moroni/Comoros than Mogadishu/Somalia (960)

- Abuja/Nigeria (452) is closer to Yaounde/Cameroon than Bangui/CAR (486)

- Yamousoukro/Ivory COast is closer to Accra/Ghana than Niamey/Niger (571)

I think I didn't explain it correctly. It's not about which capital is closer to the current one, it's about the route through all capitals which has the shortest total length. So indeed Taipei is closer to Tokyo than Palikir, but the total length of the route first visiting Oceania and then going to Taipei via the Philippines is shorter.

Accra is the best one to show this: if we'd keep going to the closest one, we'd end up in Dakar without having visited Niamey, Ouagadougou and Bamako. To visit them we'd need to backtrack before jumping to South America, then from Niamey. The total length is then a lot longer than visiting Niamey and Ouagadougou first from Accra, before continuing down the coast

found a way to reduce:

1) Skopje between Sofia and Pristina (instead of between Tirana and Athens)

2) Tokyo-Taipei-Manila-Bandar-Ngerulmud-Palikir.......P.Moresby-Dili-Jakarta-Singapore

You are indeed correct on both of those. I'll update the quiz, thank you!
