The FTC’s authority to engage in International Enforcement Co-operation is inherent in its ability to act in furtherance of its mandate. The FTC has the discretion to cooperate, including when it furthers its enforcement interests. See https://www.ftc.gov/system/files/documents/public_statements/1049863/international_guidelines_2017.pdf.  The IAEAA authorizes the FTC and DOJ to enter into antitrust-specific mutual assistance agreements with foreign authorities that allow the FTC and DOJ to share evidence relating to antitrust violations already in their possession and provide investigatory assistance in obtaining evidence, subject to certain limitations. See 15 U.S. Code Chapter 88 – International Antitrust Enforcement Assistance Act (IAEAA), https://uscode.house.gov/view.xhtml?path=/prelim@title15/chapter88&edition=prelim.
