The United Arab Emirates is to reopen its embassy in Damascus on Thursday, the UAE Foreign Ministry stated.
The embassy has been shut since the early months of Syria's
conflict, which erupted in 2011.
A ministry note to journalists invited them to cover the event at 1:30 p.m. (1130 GMT) at the embassy, located in the Abu Rummaneh district of the capital Damascus.
Earlier this month, Sudanese President Omar al-Bashir became the first Arab head of state to visit Damascus since the start of the Syrian conflict, flying into Damascus airport.
The border crossing between Syria and Jordan was reopened in October.
The Arab League suspended Syria's membership in 2011.
An Arab diplomat, speaking on condition of anonymity, told Reuters last week he believed a majority wanted Syria to return to the League - with only three or four states expected to oppose this - but there had been no official proposal yet.
Egyptian state-run media have called for Syria to be reinstated. The secretary general of the Arab League, veteran Egyptian diplomat Ahmed Aboul Gheit, said in April that the decision to suspend Syria had been "hasty".
Arab state support was funneled to Syrian rebels through a program overseen by the US Central Intelligence Agency until President Donald Trump ordered it shut down last year.
The anti-Assad rebels' last foothold is an arc of northwestern territory abutting the border with Turkey, which still supports them.
Trump last week decided to withdraw US forces that are deployed in areas of northern and eastern Syria in support of Kurdish-led militia.
Damascus has vowed to recoup control of the region currently controlled by the US-backed Syrian Democratic Forces. The area, which includes oil fields, water resources and farmland, amounts to roughly one quarter of Syria.
