A few Malaysian individuals and entities have appeared on the US State Department’s list of sanctioned entities and individuals believed to “engage in proliferation activities“.
You can check out the list here. Some of them date several years ago, and the sanctions have expired or have been lifted; a few remain active.
According to the State Department, “announcements of such sanctions determinations are printed in the Federal Register and can be accessed through the Government Printing Office web page.”
Here is one such entry in the US Federal Gazette in July 2016 that mentions a few Malaysian entities and it states:
A determination has been made that a number of foreign persons have engaged in activities that warrant the imposition of measures pursuant to Section 3 of the Iran, North Korea, and Syria Nonproliferation Act.
The Act provides for penalties on foreign entities and individuals for the transfer to or acquisition from Iran since January 1, 1999; the transfer to or acquisition from Syria since January 1, 2005; or the transfer to or acquisition from North Korea since January 1, 2006, of goods, services, or technology controlled under multilateral control lists (Missile Technology Control Regime, Australia Group, Chemical Weapons Convention, Nuclear Suppliers Group, Wassenaar Arrangement) or otherwise having the potential to make a material contribution to the development of weapons of mass destruction (WMD) or cruise or ballistic missile systems.
Have a look and see what you make of it.
