A letter by 26 human rights and environmental groups has called into question whether US companies are doing enough to fulfill reporting requirements issued by Washington, which are aimed at ensuring that businesses are not complicit in rights abuses resulting from their activities in Burma. Saying the first reports submitted by US companies “exhibit serious informational gaps,” the groups called on President Barack Obama to hold firms to a higher standard. They cited informational shortcomings on “passive investments” in Burma and the failure of one company to identify its local partner in Burma as two examples of reporting failures.
