The United Arab Emirates said on Tuesday it was forming a new military and economic committee with Saudi Arabia separate from the Gulf Cooperation Council. 
The move comes with Kuwait hosting a two-day summit of the GCC, which is riven by divisions after Saudi Arabia and its allies cut ties with Qatar earlier this year.
The committee "will co-ordinate between the two countries in all military, political, economic, trade and cultural fields," according to a decree issued by UAE President Sheikh Khalifa bin Zayed Al-Nahyan.
There was no immediate confirmation from Saudi authorities.
The two countries are close military allies, including in Yemen where a Saudi-led coalition is battling Iran-backed rebels.
Saudi Arabia, the UAE and Bahrain, together with Egypt, cut all ties with Qatar on June 5, accusing Doha of supporting extremists and of being too close to Iran. Qatar denies the allegations.
Mediation efforts led by Kuwait have failed to resolve the crisis.
