Arriving from Jakarta on the sixth day of his latest diplomatic tour, Kerry began a meeting with Abu Dhabi's Crown Prince Mohammed bin Zayed and Foreign Minister Abdullah bin Zayed. He is expected to join them later for dinner.

"They will discuss important regional issues of mutual concern including the ongoing situation in Syria," a senior State Department official said.

Earlier after meeting with Indonesian Foreign Minister Marty Natalegawa, Kerry criticized Russia for allegedly supplying arms to Syrian President Bashar al-Assad, despite committing to trying to find a political solution to end the three-year war.

The United States as well as some Arab regimes have become increasingly frustrated by the lack of progress in trying to oust Assad government and bring in a transitional government to pave the ground for the militant groups to get the power.

No date was set for a third round of peace talks and it was unclear whether they would be held at all.

Kerry also planned to brief the leaders of the United Arab Emirates on talks with Iran over nuclear issue, which are to resume Tuesday in Vienna.
