Chief Palestinian negotiator Saeb Erekat said so in a statement following a meeting with U.S. President Donald Trump's top adviser Jason Greenblatt in Jerusalem on Tuesday.
"The aim of resuming peace process has to be based on ending the Israeli occupation and establishing an independent state," said Erekat.
He also urged U.S. side to pressure on Israel to stop "undermining" the choice of two-state solution.
Greenblatt, the U.S. special representative for international negotiations, arrived in the region on Monday.
He also met Israeli Prime Minister Benjamin Netanyahu on Wednesday, amid fresh round of talks with Israeli and Palestinian leaders.
Greenblatt last visited the region in June, when he arrived with Trump's senior advisor and son-in-law Jared Kushner to push for the revival of the long-stalled peace talks.
During his visit to Israel and Palestine in May, Trump said he would pursue "the ultimate deal" between the two sides.
The last round of peace talks, brokered by former U.S. Secretary of State John Kerry, reached an impasse in April 2014, mainly over the expansion of the West Bank settlements and the Fatah-Hamas unity government.
