DEA stands for the Drug Enforcement Administration, and FAST is an acronym for its elite operational unit, the Foreign-Deployed Advisory Support Team.
Carrying large amounts of cash through customs in any country is a challenging task. However, if the flight is sanctioned by the Drug Enforcement Administration, and especially if it involves the FAST team, the plane can enter any jurisdictionally allied country without undergoing inspections.
Approval to enter is still needed, but the key issue is that there won't be any inspections. This particular pretense is exactly what Gao Guang needs right now.
