Dispute has potential to create civil war in south of Yemen and spill over into neighbouring countries

Tensions between the United Arab Emirates and Saudi Arabia over the future of Yemen and the imminent possibility of the declaration of an independent southern state have reached boiling point with Saudi Arabia in effect accusing the UAE of threatening its future security.

The dispute has the potential to create a civil war within the south of Yemen and also spill over into other disputes including in Sudan and the Horn of Africa where the two countries often find themselves backing opposite sides. Yemen could yet become only one theatre in which the two vastly wealthy Gulf states vie for political influence, control of shipping lanes and commercial access.

The UAE has been dabbling in Yemen for years due to its support for the separatist Southern Transitional Council.

Many observers, including diplomats in Riyadh, had assumed that the UAE – often thought of as the junior if more ideological partner – would back down and tell the STC to delay or jettison its plan to declare independence and instead settle for negotiations on greater autonomy or more seats in Yemen’s coalition government body, the Presidential Leadership Council (PLC).
