NEW YORK (Reuters) – The Vatican’s chief delegate to the United Nations on Wednesday said it was unclear whether the Holy See would choose to fly its flag alongside the Palestinians’ at U.N. headquarters if a Palestinian draft resolution is approved this week as expected.

The 193-nation U.N. General Assembly is due to vote on Thursday on a Palestinian draft resolution that says the flags of non-member observer states “shall be raised at (U.N.) Headquarters and United Nations Offices following the flags of the member states of the United Nations.”

Israel has urged member states to oppose the Palestinian draft resolution. U.N. diplomats say the measure is expected to pass given the widespread support Palestine enjoys among non-aligned developing nations, the largest bloc of U.N. members.

Initially, the Palestinians had presented their flag-raising initiative as a joint proposal with the Vatican, but the Holy See’s mission quickly made clear it would not co-sponsor the resolution and asked that all references to the Vatican be removed.

Archbishop Bernardito Auza, the Vatican’s permanent observer at the United Nations, ruled out the possibility that it would let its flag fly at the world body before Pope Francis’ speech before a high-level gathering of the General Assembly on Sept. 25.

“We have no intention whatsoever to do that,” he said.

Auza added that the Vatican did not co-sponsor the Palestinian resolution “because we have certainly different priorities.” He said the Holy See was undecided about whether to allow its flag to be flown at the United Nations at all.

“Whether or not the Holy See in the future would raise its flag, that question is open,” he said.

The Vatican and Palestine are the only non-member observer states at the United Nations.

Washington described the Palestinian flag initiative as “counterproductive.”

While the United States and Israel are expected to vote against the Palestinian resolution, diplomats said the 28-nation European Union was incapable of reaching a unified position.

While most EU members will abstain, more than half a dozen EU member states – including France, Sweden and others – are expected to vote for the Palestinian draft, diplomats told Reuters.

France has been spearheading a push to revive the Israeli-Palestinian peace process, which collapsed in 2014.

In 2012, the General Assembly overwhelmingly approved the de facto recognition of the sovereign state of Palestine. That came after a failed bid by the Palestinians to secure full U.N. membership.
