Tesla CEO Elon Musk and Travis Kalanick, chief exec of Uber, are joining Donald Trump's new economic advisory board.

The two tech-transportation executives have been named as members of the President's Strategic and Policy Forum, it was announced on Wednesday, alongside PepsiCo chairman and CEO Indra Nooyi.

Launched in early December, the Forum will provide economic advice, and will "be called upon to meet with the president frequently to share their specific experience and knowledge as the president implements his plan to bring back jobs and Make America Great Again," the initial announcement said.

It is being headed up by the CEO of Blackstone, Steve Schwarzman.

The American technology industry was overwhelmingly opposed to Donald Trump before the election, with particular concerns around his anti-immigration rhetoric -; Silicon Valley is heavily reliant on immigrant workers. But following his shock election, the industry is tentatively exploring how it can work with Trump.

On Wednesday, top-tier tech executives are also meeting with the president-elect at Trump Tower in New York, with attendees including Apple CEO Tim Cook, Microsoft CEO Satya Nadella, Larry Page and Eric Schmidt from Google parent company Alphabet, Amazon boss Jeff Bezos, Facebook COO Sheryl Sandberg, and others.

During the election, Elon Musk, who is CEO of electric car company Tesla and aerospace firm SpaceX supported Hillary Clinton and was critical of Trump, saying that "I think a bit strongly that [he] is probably not the right guy" to be president. Travis Kalanick, CEO of ride-hailing company Uber, has also joked about the Republican president-elect, saying in 2015: "Oh my god, Donald trump’s gonna win. I’m going to move to China if Donald Trump wins."
