Thanks Matt for pointing out the website for GEMAP, which is the international/Liberian partnership against corruption that's overseeing the country's economic affairs and building local capacity for good economic governance.
The FAQ page looks designed to allay any fears that Liberia has given over its sovereignty to foreigners.
Their twice-monthly reports are posted in MS word format here. This month's report talks about mineral rights contracts that they're reviewing, and how they're concerned about financial problems at the port.
GEMAP has billboards around Liberia encouraging people to pay their taxes and to trust the new government's economic management.
