The EU "was supposed to allocate to international organizations, not us, €6 billion [$6.87 billion], using a 3+3 installment system," Erdoğan told a meeting of business leaders in Budapest, Hungary.
But, he added, "they only gave out €1.7 billion [$1.94 billion]. Despite all that, we continue our services."
Speaking at a Turkey-Hungary Business Forum meeting, Erdoğan highlighted how Turkey currently hosts some 3.5 million Syrian refugees, more than any country in the world.
The president also said Turkey has footage of refugees being left for dead in the Mediterranean and Aegean seas.
"I say it sadly, the international community failed to fulfill its responsibility to find a solution to the refugee issues," said Erdoğan, on the last day of a two-day visit to Hungary.
"Our 'safe zones' proposal that could have saved hundreds of thousands of lives and managed to prevent displacing millions of Syrians was deliberately sabotaged, especially by our allies," Erdoğan said.
"The bill for this deadlock is firstly being paid by the Syrian people, then by neighboring countries like Turkey," he said.
Turkey has spent more than $33 billion from its own national resources to help and shelter some 3.5 million refugees since the beginning of the Syrian civil war, according to UN figures.
