RAMALLAH - Israel must chose between "settlements or peace," Palestinian chief negotiator Saeb Erakat said on Monday ahead of the September 2 restart of negotiations in Washington.
"The choice of the Israeli government is settlement or peace, they cannot have both," he said at a news conference in Ramallah, the political capital of the Israeli-occupied West Bank.
But he also said he believed agreement could be reached within one year.
"We think it is doable."
Palestinian president Mahmud Abbas, in a letter to EU foreign policy chief Catherine Ashton dated August 21 and seen by AFP on Monday, also warned that the talks would be cut short if Israel resumes settlement activities.
Both sides agreed to relaunch direct negotiations after a 20-month hiatus, even though the Palestinians had initially insisted they would not hold face-to-face talks unless the Israelis freeze settlement activity in the West Bank, including Jerusalem.
But Erakat made it clear on Monday that settlements remain a major issue, and that it now remains to be seen whether Israel will renew a 10-month moratorium on settlement construction it imposed in November last year.
"If Mr Netanyahu decides to renew settlement tenders come September 26, he will have decided to stop negotiations," he said.
Prime Minister Benjamin Netanyahu has indicated in the past the moratorium would conclude on that date.
And Vice Prime Minister Silvan Shalom reiterated on Monday that the moratorium was unlikely to be renewed.
"I don't think the freeze will be extended," he told public radio.
"The Palestinians cannot use this as a pretext to suspend negotiations," he warned.
The international community has pressed Israel to halt settlement activity while Netanyahu is under pressure at home to allow construction to resume.
