Otherwise, US Treasury Secretary Steven Mnuchin said that President Donald Trump's administration seeks to wrap up the tax reform agenda by the end of 2017, adding that he doesn't know whether Trump's goal to cut corporate taxes to 15% is achievable due to budget constraints, but he asserted on the importance of reaching record competitiveness. 

On Thursday, the Senate Financial Committee will hold a session to hear tax reform propositions, after Senator Orrin Hatch said he expects the plan to be shared with other senators, while Trump urged Congress to vote on the reforms as fast as possible without waiting until the end of September. 

Back to Mnuchin, who expressed his concerns regarding the US debt ceiling passing $20 trillion, and adding that recent Hurricanes Irma and Harvey will impact the US GDP growth, while noting that recovery will happen soon after from their damages. 

Finally, Mnuchin stated that he's working with Trump currently on the issue of the next Federal Reserve governor, as Janet Yellen's term nears its end in February, adding that Yellen is one Trump's candidates to continue leading the central bank, before moving on to the North Korea nuclear issue, saying that if China doesn't apply the sanctions imposed by the UN Security Council on North Korea, sanction will imposed upon the world's second economy.
