RAMALLAH (Reuters) - Palestinian President Mahmoud Abbas on Saturday cautiously welcomed a French proposal to convene Israeli and Palestinian negotiators in Paris to try to renew collapsed peace talks. French FM Alain Juppe this week offered to host talks to discuss ideas for a Palestinian state raised last month by US President Barack Obama, aiming to avert a showdown at the United Nations in September. "We said that in principle that this initiative is acceptable," Abbas told Reuters, two days after his talks with Juppe in the West Bank city of Ramallah. Abbas said the French plan "talks about President Obama's vision ...in which he spoke about a (Palestinian) state with the '67 borders with borders with Israel, Egypt and Jordan."
