The Houthi threat to Saudi oil exports comes as Japan, South Korea and the Philippines are still reeling from the closure of the strait of Hormuz

Governments in Asia are scrambling to avoid their second major energy crisis in six months, as another maritime chokepoint in the Middle East faces a violent blockade, leaving only the Suez canal completely open for the free movement of gulf oil.
