Qatar took the final step on Wednesday to start litigation at the World Trade Organization in its row with the United Arab Emirates, but no other WTO members supported its move, which many trade experts see as a dangerous precedent.

The UAE was one of four countries - along with Saudi Arabia, Bahrain, and Egypt - that cut ties with Qatar, a major gas supplier and site of the biggest U.S. military base in the Middle East, on June 5. They accused Qatar of financing militant groups in Syria and allying with Iran, their regional foe.

Qatar denied the allegations and opened WTO dispute proceedings against the UAE, Saudi Arabia and Bahrain. It pressed its case against the UAE alone, and last month it asked the WTO to set up an adjudication panel.
