Name all countries that have a parcel of land that is physically separate from the country's mainland and shares one or more land borders with other countries, but not the country's mainland.
Bodies of water (except canals) can separate the exclave from its mainland.
Belgium has enclaves in the Netherlands (Baarle-Hertog), Netherlands has enclaves within those enclaves. Same, but even more complicated along the India-Bangladesh border.
As much as I like the theme of this quiz, I would appreciate if you completed the list. Further to the ones mentioned by user ponnuki above, these ones are missing: Germany (Busingen), TR Northern Cyprus (depending on whether you accept TRNC sovereignty), UAE (a counter-enclave within the Omani enclave), Uzbekistan, Tajikistan, Malawi (2 islands), Spain (Llivia), Bosnia Herzegovina (Sastavci), Israel (depending on whether you accept Palestinian sovereignty), Croatia (Brezovica), Italy (Campione d'Italia) and 3 Argentinean islands in Paraguayan waters.
The Argentinian and Malawian islands don't count because they don't have a land border with another country.
The UN doesn't recognize Turkish Northern Cyprus, and because the Palestinians aren't officially recognized with their own sovereign lands, I didn't include Israel, either. Everything else, though, has been updated. Thanks for your input!
PS: France? Don't you mean the other way round, with Llivia being a Spanish exclave? Otherwise I believe France only has domestic exclaves (Valréas). I cannot recall an international one.
Indeed, see https://en.wikipedia.org/wiki/Indo-Bangladesh_enclaves. There's even an Indian enclave within a Bangladeshi enclave which is within an Indian enclave...
