Cultural Property Agreements (CPAs) between the United States and foreign governments help to stop criminal activity at US borders by keeping looted and stolen art and artifacts out of American markets. Under US and international law, the United States can join CPAs to prevent looted and stolen antiquities and artifacts from entering the US art market, thereby fighting the illicit trade while allowing the legal trade to continue and even thrive. Moreover, bilateral agreements aim to lessen global demand for illicitly obtained or looted objects—especially because the United States makes up 42% of the legal global art market—while increasing responsible cultural exchange. The United States has signed CPAs with a growing number of countries around the world—generating mutual respect, strengthening global law enforcement, and protecting archaeological heritage in situ. From its inception, a key priority for the Antiquities Coalition (AC) has been shutting down markets to illicit antiquities, while increasing responsible cultural exchange. This article discusses the importance of barring antiquities traffickers from the multibillion US art market through legislation, international agreements, and executive orders—protecting both American consumers and our world heritage.
