Kuwait City, Dec 5 (AP): The United Arab Emirates Tuesday announced it has formed a new economic and partnership group with Saudi Arabia, separate from the Gulf Cooperation Council, a move that could undermine the council amid a diplomatic crisis with member state Qatar.

The Emirati Foreign Ministry announcement, just hours ahead of a GCC meeting in Kuwait, said the new "joint cooperation committee" was approved by the UAE's ruler and President, Sheikh Khalifa bin Zayed Al Nayhan.

Saudi Arabia did not immediately report on the new partnership.

It wasn't immediately clear how the development could affect the six-member GCC meeting, which is expected to focus on the Qatar issue. Half of the GCC members are boycotting Doha in a dispute that's cleaved the Arabian Peninsula.

The Emirati ministry said the new "committee is assigned to cooperate and coordinate between the UAE and Saudi Arabia in all military, political, economic, trade and cultural fields, as well as others, in the interest of the two countries."

The UAE and Saudi Arabia have cultivated even-closer ties in recent years. Emirati troops are deeply involved in the Saudi-led war in Yemen.

Abu Dhabi's powerful crown prince, Mohammad bin Zayed Al Nayhan, also is believed to have a closer relationship with Saudi Arabia's young Crown Prince Mohammed bin Salman.

The Emirati announcement did not say whether any other Gulf Arab countries would be invited to join the new group but the development puts pressure on the GCC, a group of American-allied Gulf Arab nations formed in part in 1981 as a counterbalance to Shiite power Iran.

The United States and its European allies all have told the council's members that the region remains stronger with them working together as a whole, while the countries themselves still appear divided over their future.

The fact the GCC meeting in Kuwait was to take place at all is a bit of a surprise, given the unusually sharp criticism among the typically clubby members of the GCC pointed at Doha.

"This is the most important annual summit the GCC has held for more than two decades," said Kristian Coates Ulrichsen, a research fellow at the James A. Baker III Institute for Public Policy at Rice University. "The GCC needs to illustrate its relevance after having been bypassed at every stage of the Qatar crisis."

The dispute began in June, following what Qatar described as a hack of its state-run news agency that saw incendiary comments attributed to its ruler, Sheikh Tamim bin Hamad Al Thani.

Soon after, GCC members Bahrain, Saudi Arabia and the United Arab Emirates closed off their airspace and seaports to Qatar, as well as the small peninsular nation's sole land border with Saudi Arabia.

The boycott initially reeled Doha, though it soon replaced food products with those flown in from Turkey and Iran.

However, Qatar's foreign reserves have dropped by some USD 10 billion, a fifth of their value, since the dispute began.

Those reserves are crucial in supporting the nation's riyal, which is pegged to the US dollar, as well as funding the upcoming 2022 FIFA World Cup that Doha will host.

For boycotting nations, they allege Qatar funds extremist groups and has too-cozy ties to Iran.

Qatar has long denied funding extremists but it restored full diplomatic ties with Iran during the crisis.

Doha shares a massive offshore natural gas field with Tehran that gives its citizens the highest per-capita income in the world.

A similar dispute involving Qatar erupted in 2014. But this time positions have hardened against Qatar, whose support for Islamist opposition groups has angered the Arab nations now boycotting it.

The UAE in particular views Islamists as a threat to hereditary rule in its federation of seven sheikhdoms. Egypt, angered by Qatar's support for the Muslim Brotherhood and the nation's deposed President Mohammed Morsi, is also boycotting Doha.

The US, which has some 10,000 troops stationed at Qatar's sprawling al-Udeid Air Base as part of its campaign against the Islamic State group and the war in Afghanistan, also has sought to end the crisis.

Its military has halted some regional exercises to put pressure on the GCC to resolve the crisis. However, President Donald Trump in the meantime made comments seemingly supporting the Arab nations' efforts at isolating Qatar, complicating those efforts.

A Trump-prompted call in September between Qatar's Sheikh Tamim and Saudi Crown Prince Mohammed bin Salman that offered a chance at negotiations also broke down in mutual recriminations.

Kuwait's 88-year-old emir, Sheikh Sabah Al Ahmad Al Sabah, has tried to mediate the dispute, so far without success. However, Kuwait appeared in recent days to secure promises from the GCC to attend its annual high-level summit.
