Russia backed a Palestinian proposal for a Middle East peace conference, suggesting Tuesday it could be held at ministerial level in spring or summer, as the US said it would move towards renewing ties with the Palestinians under Joe Biden.

The United States -- which had firmly sided with Israel under the administration of Donald Trump -- said Tuesday it intended to "restore credible U.S. engagement with Palestinians as well as Israelis."

Recalling that Moscow had backed Palestinian leader Mahmud Abbas' idea for international talks in early 2021 when he first proposed it in September, Russia's foreign minister Sergei Lavrov offered ideas about who could be invited.

"We propose holding an international, ministerial-level meeting in spring-summer 2021," Lavrov told a UN Security Council meeting about the Middle East held by videoconference.

The roughly 10 participants would include Israel, the Palestinians, the four members of the so-called Middle East diplomatic quartet (Russia, the United Nations, the United States and the European Union), along with four Arab states -- Bahrain, Egypt, Jordan and the United Arab Emirates, Lavrov said.

"It would also be important to invite Saudi Arabia, which is behind the Arab peace initiative," he added, without offering a specific date or site for the eventual conference.

He noted that Moscow remained ready to host a meeting between Israel and the Palestinians in the Russian capital "at the highest levels."

China voiced its support for Russia's idea at the UN meeting, but most other participants did not offer an opinion on the proposal.

Credible US engagement

At last year's annual meeting of the UN General Assembly, Abbas -- who had rejected a peace plan advanced by then US president Trump -- said the Israeli-Palestinian conflict needed to be resolved on the basis of international law, and under conditions agreed by the global community.

On Tuesday, nearly all who spoke at the Security Council meeting, including the United States, reaffirmed the need for a two-state solution -- under which Israel and a future Palestine would coexist.

"The Biden administration will restore credible US engagement with Palestinians as well as Israelis," said Washington's interim UN envoy Richard Mills.

The new Democratic president "has been clear in his intent to restore US assistance programs that support economic development and humanitarian aid for the Palestinian people and to take steps to re-open diplomatic missions that were closed by the last US administration," he added.

Under Trump, the US had stopped supporting the UN Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) and closed the Palestinians' liaison office in Washington.

In a joint statement the Security Council's European members -- Estonia, France and Ireland -- urged Israel to "show leadership" in moving towards a solution with the Palestinians, and called on both sides to engage in trust-building.

For the first time in 15 years, the Palestinians are set to hold elections -- legislative polls on May 22, followed by a presidential election on July 31.
