Lebanon opened its first embassy in Syria on Monday, five months after the neighbours established diplomatic ties following decades of turbulent relations.

but don't get your hopes up ...

No Syrian officials attended the opening ceremony and no speeches were made. Syrian media took very little notice of the opening. State-run news agency SANA — which generally reflects the thinking of the government — mentioned the inauguration, but in few words.
Syrian Foreign Minister Walid al-Muallem blamed the notable official absence on a scheduling conflict.
"It was not intentional," he told a joint news conference with visiting Arab League secretary-general Amr Moussa at the end of day-long Arab Foreign Ministers' meeting on the Middle East peace process.
"We had learnt first the inauguration was taking place on Sunday, not Monday," he said.
