EU countries have shied away from taking in refugees, preferring instead to give Syria's neighbors money to support those fleeing the violence so they would stay close to their country.
Belgium's Foreign Minister Didier Reynders visited refugees in the Turkish province of Kilis on Tuesday, and stressed the need for "the international community to help."
Turkish Finance Minister Mehmet Simsek said his country has so far spent some $220 million to aid the refugees in Turkey.
The number of Syrian refugees in Turkey has recently passed 100,000, according to government officials.
Also on Tuesday, Turkey's Prime Minister Recep Tayyip Erdogan discussed Syria's conflict with Iranian President Mahmoud Ahmadinejad on the sidelines of a regional conference in Baku, Azerbaijan.
After his return to Ankara, Erdogan told reporters that they had discussed ways to help end the conflict. He did not elaborate.
Iran has been one of Assad's staunchest backers throughout the uprising.
Turkey also initially backed Assad, but then called on him to step down, and lent its support to the rebels. The two neighbors have traded artillery fire over their border in the past week.
