United Arab Emirates–Yemen relations
The United Arab Emirates and Yemen have a complex and strained relationship, as the UAE has played a significant role in regional politics in Yemen, and has at various points been an adversary of the country, as the UAE's involvement in Yemen, for example the United Arab Emirates takeover of Socotra, and its support for the Southern Transitional Council, a secessionist organization in Southern Yemen, has been a source of tension between the two countries, and has contributed to the ongoing conflict and humanitarian crisis in the country. Furthermore, the UAE has been involved in other efforts in Yemen that have been controversial.
