WASHINGTON, May 6 (Reuters) - The United States will not normalise relations with the government of Syrian President Bashar al-Assad, the State Department has said, as many of Washington’s Arab allies re-establish ties with Damascus.

The State Department said late on Thursday that top US diplomat Antony Blinken discussed a recent meeting in Amman between Syria and its Arab neighbours during a phone call with his Jordanian counterpart, Ayman Safadi.

“Secretary Blinken made clear that the United States will not normalize relations with the Assad regime and does not support others normalizing until there is authentic, UN-facilitated political progress in line with UN Security Council Resolution (UNSCR) 2254,” the department said.

The 2015 resolution calls for free and fair elections in Syria under UN supervision.

The foreign ministers of Syria, Egypt, Iraq, Saudi Arabia and Jordan met for talks in the Jordanian capital on Monday amid a push to bring al-Assad’s government back into the Arab fold.

Syria was suspended from the Arab League and ostracised by regional powerbrokers in 2011 after its crackdown on Arab Spring protests, which turned into a protracted war. The conflict has killed hundreds of thousands of people and displaced millions.

As the Syrian government regained control over large parts of the country – with support from Iran and Russia – some Arab countries began to soften their stance towards Damascus.

The US, however, has maintained that it would not change its opposition to al-Assad without an inclusive political settlement to the conflict.
