US President-elect Donald Trump has expressed willingness to work with Russia and China.
Donald 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 US no longer acknowledges Taiwan, was up for negotiation.
Meanwhile, a US 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 extremism and in other matters.
