The increased demand for Asian art in the West has led to rising nationalism and desire of source countries to protect their national treasures from being exported for sale at auction. An increased global awareness of unethical trade practices in Asian art leads to the establishment of organizations preventing international illicit art trade, an increased focus on the protection of cultural property in existing international diplomatic institutions, and more exacting legislation defining ownership of cultural property. These developments empower countries from which art has been illegally removed, resulting in a rise in restitution claims, and in turn, a higher demand for detailed provenance research in the western art field. My research focuses on the rise of restitution claims and its effect on Asian art trade and collection practices in London. I aim to become familiar with judicial, institutional, and academic efforts to protect source countries from being victimized by illegal trade, and how they encourage source countries of art to file restitution claims against collectors, museums, and national governments. As a result of increased restitution claims, provenance research and authentication practices have become more sophisticated in museums, auction houses, and private galleries. My second research goal is to understand these authentication methods, their development, and practice.
