US President Donald Trump’s trade policy looks incoherent. Last year, he withdrew his country from the almost concluded negotiations to form the Trans Pacific Partnership. The other partners have gone forward, nonetheless, and now Trump has asked his staff to consider rejoining that alliance. In April, the president imposed tariffs on steel and aluminium imports, only to fast exempt many countries temporarily. At the same time, he threatened another host of tariffs on Chinese imports. Where this all will lead to is unclear, but one thing is certain: uncertainty has grown dramatically. The Indonesian economist Iwan J. Azis assessed matters in an interview.
