18 Andrew J Weinschenk, Division for Counter Threat Finance and Sanctions
The acting deputy assistant secretary of state heads the US department that develops the policies that shape sanctions on Iran and Venezuela, which continue to influence and reshape global shipping markets
If not for Donald Trump's failure to secure a second term, Mr Weinschenk's Top 100 debut would have gained a much higher ranking; his department is charged with implementing Iranian and Venezuelan-related sanctions on oil and shipping. It is unlikely US president-elect Joe Biden will match his predecessor’s hardline stance, with sanctions likely to be watered down over 2021
