Taiwan is in Asia. It is an Island, so not a part of any continent but it is in Asia.Taiwan is not part of a continent but it is an island that lies near China so you could possibly qualify it as part of Asia but I am not positive about this answer.

The smallest island in Asia is Pulau Upeh in Malaysia, with an area of about 0.2 square kilometers.
Asia
Kastelorizo is in Europe and NOT in Asia. It is a Greek Island that belongs to Greece and is situated between The Island of Rhodos in Greece and the Island (Country of Cyprus) in the Mediterranean Sea.
