Donald Trump, Jr. attended talks in Paris in October about partnering with Russia to end the bloody Syrian conflict, it was revealed Wednesday, in just the latest installment of Trump family members carving out a substantive portfolio as President-elect Donald Trump prepares to take office.

Thirty people attended the event at the Ritz in Paris, the Wall Street Journal reported. Among them were think tank founder Fabien Baussart and his wife, Randa Kassis, who as the paper reported is a leader of a Syrian opposition group that is backed by the Kremlin.

Russia has strongly backed Syrian President Bashar al-Assad and has been using its military might to attack rival opposition groups using air power. Kassis' group seeks a political transition through cooperation with Assad.

Kassis told the paper from Moscow, 'We have to be realistic. Who’s on the ground in Syria? Not the U.S., not France. Without Russia, we can’t have any solution in Syria.'

Of the president-elect’s son, she said: “I think he’s very pragmatic and is flexible.”

Kassis wrote about the meeting on her Facebook page two weeks ago. 'Syria's] opposition got hope that political process will move forward and Russia and the United States will reach accord on the issue of the Syrian crisis, because of Trump's victory,' she posted. 'Such hope and belief is the result of my personal meeting with Donald Trump junior in Paris in October.'

In addition to reinforcing President-elect Trump's frequent statements of support for Russia and Russian President Vladimir Putin, the meeting signals the wide-ranging portfolios Trump family members have carved out.

Trump told the New York Times on Tuesday that son-in-law Jared Kushner could help make peace between Israel and the Palestinians, when asked a question about Kushner's role.

By surrounding himself with family members as top envoys and advisors, Trump is being compared to Nicaraguan President Daniel Ortega, who was reelected this month with his wife Rosario Murillo running as his vice president

'I would love to be able to be the one that made peace with Israel and the Palestinians. I would love that, that would be such a great achievement. Because nobody’s been able to do it,' Trump said.

Pressed on Kushner's role, he said: 'Well, I think he’d be very good at it. I mean he knows it so well. He knows the region, knows the people, knows the players. I would love to be — and you can put that down in a list of many things that I’d like to be able to do.'

Kushner is a successful real estate developer. He has been a donor to the pro-Israel lobby AIPAC. Kushner is an orthodox Jew, his wife, Ivanka Trump, converted to Judaism.

The extent of his involvement in Middle East peace issues isn't known. His parents, Charles and Seryl Kushner, donated $20 million to the Shaare Zedek Medical Center in Jerusalem, announcing the gift on their 40th wedding anniversary. The medical campus was renamed after them following the gift.

Trump's decision to involve his family in high level consultations – he has said he wants to hand of the Trump organization business to them, although he hedged in a recent Times interview about how he would handle the business – has drawn criticism from those fearful it might signal a move toward the appearance of corruption.

'It’s sort of like Donald Trump appearing to go down the same path as Daniel Ortega the Sandanista,' said Dr. Louis Goodman, former dean of the School of International Service at American University.

Ortega was reelected to a fourth term on November 7, a day before Trump's stunning electoral win. The former guerrilla leader ran on a ticket with his wife Rosario Murillo as vice president, and appointed his children as his closest advisors.

'One hopes that that’s not going to happen that there’ll be protection, that this won’t contribute to what commentators have talked about for centuries – the creation of an oligarchy and the creation of inequality and slowing down economic growth,' Goodman added.

When the president-elect met with the Prime Minister of Japan at Trump Tower last week, Ivanka Trump was pictured in the official photo that the Japanese government released.

'What’s his daughter doing there?' Jordan Liebowitz of Citizens for Responsible Ethics in Washington told DailyMail.com. 'What is she there to represent? Because if she’s running the business, why is he having someone representing his business interest at a meeting with the foreign leader.'

Trump met last week with Indian business partners in one of his luxury hotel projects, the Economic Times of India reported.
