The drafters of the CPIA contemplated that import restrictions would give breathing space for source countries to get their own house in order, but they were never supposed to go on forever. Yet, the State Department and US Customs have extended import restrictions on Peruvian goods for the fourth time. So, Americans have been limited in their ability to import Peruvian goods from third countries for yet another 5 years.
The extension expands restrictions to colonial era manuscripts although it is dubious that they meet the definition of ethnological objects under the CPIA. Presumably, the restrictions were put into place to keep Peruvian citizens from selling off old manuscripts to foreigners. Materials within Peruvian institutions are already restricted from entry in the US under the CPIA's stolen property provisions.
