Donald Trump, has said he is willing to work with Russia and China if they cooperate.

Mr. Trump told the Wall Street Journal that newly-imposed sanctions on Russia would remain “at least for a period of time” but could then be lifted.

He also said the “One China” policy, in which the U.S no longer acknowledges Taiwan, was up for negotiation.

Meanwhile, a U.S Senate committee will probe claims Russia attempted to meddle in the presidential election.

In his interview, Mr. Trump said sanctions on Russia could be lifted if Moscow helped Washington in the war against Islamic extremism and in other matters.

“If you get along and if Russia is really helping us, why would anybody have sanctions if somebody’s doing some really great things?”

The president-elect said he hoped a meeting with President Vladimir Putin would be arranged.

With regards to Beijing, Mr. Trump said China had to allow U.S companies to compete by floating its currency.

But he said he would not label China a currency manipulator the instant he took office.

The BBC reports that he had already questioned the “One China” policy last month, provoking angry responses in Chinese state media.

Republican and Democratic leaders on the Senate Intelligence Committee vowed to follow their investigation “wherever it leads.”

They will examine Russia’s cyber activity and intelligence practices.
