The Hamburg G20 Leaders’ Statement on Countering Terrorism

The G20 in addressing measures needed for fighting terrorism finance mentions the antiquities trade:

10. We underline our resolve to make the international financial system entirely hostile to terrorist financing and commit to deepening international cooperation and exchange of information, including working with the private sector, which has a critical role in global efforts to counter terrorism financing. We reaffirm our commitment to tackle all sources, techniques and channels of terrorist financing and our call for swift and effective implementation of UNSCR and the Financial Action Task Force (FATF) standards worldwide. We call for strengthening measures against the financing of international terrorist organisations in particular ISIL/ISIS/Daesh, Al Qaida and their affiliates. [...] 

16. We call upon countries to address all alternative sources of financing of terrorism, including dismantling connections, where they exist, between terrorism and transnational organized crime, such as the diversion of weapons including weapons of mass destruction, looting and smuggling of antiquities, kidnapping for ransom, drugs and human trafficking. 

Good luck in working with the private sector there, the international antiquities trade is in utter denial that the no-questions-asked buying and selling of antiquities is anything but a good thing. The world knows differently.
