Israeli PM Benjamin Netanyahu says his country will retaliate if the Palestinians take further unilateral steps in pursuit of statehood.
He told a weekly cabinet meeting that Israel would not continue peace talks with the Palestinians at any price.
Palestinian leader Mahmoud Abbas has applied to 15 UN conventions, accusing Israel of backtracking on its promises.
US envoy Martin Indyk is to meet both sides on Sunday to try to breathe new life into the embattled peace process.
Earlier this week, Israel cancelled plans to free a final batch of Palestinian prisoners, arguing that Mr Abbas’s decision to sign up to several international conventions at the UN had violated the conditions for the release.
