The United Nations General Assembly is expected to decide late Thursday whether to upgrade the status of the Palestinian Authority at the world body from an entity to a non-member state.
Delegates from member nations say support is strong for the upgrade, but it will lack the backing of some key countries, including the United States. More than 60 countries are co-sponsoring the resolution.
Palestinian Authority President Mahmoud Abbas will address the General Assembly before the vote. The Palestinians are expected to obtain well more than the required simple majority of the 193 U.N. member states present and voting.
The United States firmly opposes the move, saying the only road to statehood for the Palestinians is through direct negotiations with Israel.
Senior U.S. State Department officials met Wednesday with President Abbas in New York in a last-minute effort to urge him to reconsider the move in the General Assembly.
U.S. State Department spokeswoman Victoria Nuland said Deputy Secretary of State William Burns and Special Envoy for Middle East Peace David Hale were at the meeting.
“The deputy secretary also reiterated that no one should be under any illusion that this resolution is going to produce the results that the Palestinians claim to seek," Nuland said.
In Washington, Secretary of State Hillary Clinton said Wednesday the United States has made very clear to the Palestinian leadership that it opposes the upgrade.
“The path to a two-state solution that fulfills the aspirations of the Palestinian people is through Jerusalem and Ramallah, not New York,” she said.
The status would allow Palestinians access to the International Criminal Court, where they could ask the prosecutor to investigate Israel's actions in their territories.
Israel discounts move
Israeli Prime Minister Benjamin Netanyahu on Thursday downplayed the Palestinians' attempt saying it will not help them achieve their long-promised state.
"The decision at the United Nations today won't change anything on the ground," Netanyahu said at a ceremony in Jerusalem. "It won't promote the establishment of a Palestinian state; it will distance it."
Granting Palestinians the title of "non-member observer state'' falls short of full U.N. membership, something they failed to achieve last year.
British Foreign Secretary William Hague told lawmakers Britain would consider embracing the request, but only if the Palestinian Authority could give him some key assurances - including pledges to return to negotiations with Israel and to not pursue its grievances with Israel in international courts.
Still, the Palestinians may also lack the support of some key European countries.
Germany has announced it will abstain. France has said it will vote "yes" for the non-member state status, but many other European Union countries have not yet announced how they will vote.
