Sending a forceful message to Israel's prime minister and the incoming Trump administration in the U.S., dozens of countries called Sunday on Israel and the Palestinians to revive work toward long-elusive peace — including an independent Palestinian state.

The closing declaration at a Mideast peace conference in Paris urged both sides to "officially restate their commitment to the two-state solution" and disassociate from voices that reject this. It also warned them against taking one-sided actions that could hurt talks, an apparent reference to Israeli settlement building.

While the Palestinians welcomed Sunday's declaration, Israeli Prime Minister Benjamin Netanyahu called the conference "rigged" and cooked up behind Israel's back to force it to accept conditions against national interests.

The French organizers argued the conference, which included representatives from more than 70 countries including Canada, was necessary to keep hopes alive for a two-state solution between Israel and the Palestinians — the solution favoured by much of the international community for the past two decades.

"We are determined to support peace in the region, a two-state solution built by the two parties and supported by their‎ people," a spokesperson for Global Affairs Canada said.

Condemning Palestinian 'terror'

Many members of Netanyahu's coalition want to abandon the two-state solution and expand settlements, and some have even called for annexing parts of the West Bank. Trump's campaign platform made no mention of Palestinian independence.

In a nod to Israel, the final declaration of Sunday's conference included criticism of incitement and "terror," a reference to Palestinian attacks. And some of the pro-Palestinian language in an earlier draft was removed after diplomats huddled in Paris on Sunday.

U.S. Secretary of State John Kerry, who has been increasingly critical of Netanyahu, represented the U.S. at Sunday's talks and defended the effort.

He rejected Israeli criticism of the conference, saying the concept of a two-state solution to the conflict is "threatened" and must be reinforced if it is ever to happen. The communiqué​, he said, endorses that without imposing a resolution.

"Given where things are going and what is happening, that is particularly important," he said.

Moving the embassy

He also warned that it's too early to move the U.S. Embassy in Israel from Tel Aviv to contested Jerusalem, as proposed by U.S. president-elect Donald Trump. "This is not the right time," he said. "We think it's ill-advised."

While Netanyahu has voiced support for a two-state solution, his critics, including Kerry, have said that continued settlement construction on occupied territories raises questions about his commitment to pursuing a peace deal.

Palestinian official Saeb Erekat said Sunday's statement amounted to a rejection of Israel's settlement construction in occupied territories. He said it sent a message that Israel "cannot achieve peace and stability" without ending its settlements.

Will Trump condone settlements?

France and others expressed concern that the Trump administration could unleash new tensions in the region by condoning settlements on land claimed by the Palestinians and by moving the U.S. Embassy.

French Foreign Minister Jean-Marc Ayrault said such a move would be a "provocation" and could spark new violence. But the issue wasn't mentioned in the final declaration.

French President François Hollande said he was sounding an "alert" that peace talks should be revived for "the security of Israel, security of all the region" before violent extremists and Israeli settlements destroy any hope of a two-state solution.

"It is not a question of dictating to the parties," Hollande insisted. "Only direct negotiations between Israelis and Palestinians can lead to peace. No one will do it in their place.

"The world cannot, should not resign itself to the status quo," he told the gathered diplomats from across Europe, the Mideast and other regions, as well as from the United Nations, the Arab League and other international organizations.

Hollande urged them to support peace efforts by offering economic incentives to Israelis and Palestinians.

'Last flutters of yesterday's world'

Netanyahu declined an invitation to a special meeting after the conference, and Palestinian leader Mahmoud Abbas was initially expected, but his visit to Paris was postponed. Abbas is the president of the Palestinian Authority, which governs the Palestinian territories.

The Israeli prime minister said the gathering would do little to promote peace and marked the "last flutters of yesterday's world."

"Tomorrow will look different and tomorrow is very close," he said in apparent reference to Trump's incoming administration.

Israeli and Palestinian leaders have not negotiated even indirectly since a failed U.S.-led peace effort in 2014.

Paris protests

While the conference was underway, a few hundred pro-Israel demonstrators, waving Israeli flags and placards denouncing the summit, gathered outside Israel's embassy in Paris.

"The Palestinians and a number of Arab states have not expressed a will for peace," Serge Klarsfeld, a well-known French Nazi hunter, said. "If it existed and if the Arab world recognized the existence of Israel, we would find the means to solve all the problems very quickly.
