Italy, Malta, Greece and Spain the main gateways for refugees from the south had pushed for the topic to be put on the meeting's agenda in the hopes of achieving better burden-sharing, but the talks yielded neither concessions from northern Europeans nor more funding for EU border patrol agency Frontex.
Germany and others pointed out that they already receive significantly more asylum applications per capita than Italy and other southern countries.
Thousands of migrants reach Italy's shores every year, but they often use the country only as a transit point. Germany received about 80,000 asylum applications in 2012, while Italy registered 16,000, according to EU statistics.
In their concluding statement, the leaders said they expect to discuss the findings of the newly-setup migration task force at their next summit in December.
They also stressed "the importance of addressing root causes of migration flows by enhancing cooperation with the countries of origin and transit, including through appropriate EU development support and an effective return policy."
Human rights groups condemned the EU's inaction.
It "painfully shows that the expressions of sadness and solidarity were nothing more than crocodile tears" Amnesty International official Nicolas Beger said.
"Europe's priority clearly is not to save lives or to protect people along the borders. Instead it is to prevent people from arriving in Europe at all costs, even if those people are in need of safety and protection," he added.
Advocacy groups like Human Rights Watch have urged the EU to increase its sea patrols and discourage clandestine crossings by smugglers by guaranteeing that anyone picked up at sea will be taken to a safe European port.
Some European officials, however, have argued that making boat migration safe will amount to an open invitation, thus increasing the number of refugees risking their life while crossing the Mediterranean.
