The European Union has reaffirmed its commitment to providing economic and political help to Palestinians as it called again for an end to violence.
Mahmoud Abbas hopes the EU will continue to back Palestinians
After talks with Palestinian leader Mahmoud Abbas, European Commission President Jose Manuel Barroso said there was a good opportunity for peace.
But he said both Israel and "terrorist movements" must end their attacks.
The talks in Brussels followed Tuesday's international conference in London on the Palestinians' future.
Israel has said it welcomes this international involvement but adds that Palestinian leaders must be pressed to tackle what Israel calls terrorism.
On Wednesday, Mr Barroso said the EU had told Israel and the US of its disappointment that the Israeli army had destroyed projects supported by the EU.
He confirmed that the EU would provide more than $300m (228m euros; £156m) to the Palestinian Authority.
Earlier, Mr Abbas met the EU foreign policy chief, Javier Solana, who welcomed the renewed hope for peace in the Middle East and promised continued support for the Palestinian Authority and the roadmap peace plan.
"The European Union is going to be behind the Palestinian people for the realisation of their dream," Mr Solana said.
"The dream is clear: to have one state and a state that can live together in peace with the neighbouring state of Israel."
Mr Abbas thanked the EU for its support.
"We are talking about a new era of peace and hope. And I hope that this support will continue," he said.
"Let's be optimistic. Let's remain optimistic."
