The Arms Trade Treaty (ATT), adopted by the UN General Assembly on 2 April 2013 and entered into force on 24 December 2014, regulates the international trade in conventional arms. While most of its obligations apply to transfers that physically cross a state party's borders, several provisions reach activities that occur outside national territory — what practitioners call extraterritorial controls.
The clearest extraterritorial reach appears in Article 10 (Brokering), which requires each state party to "take measures, pursuant to its national laws, to regulate brokering taking place under its jurisdiction." Because brokers often arrange deals between two foreign countries without the weapons ever transiting the broker's home state, regulating their activity is inherently extraterritorial. The treaty leaves states discretion on how to do this — through registration, licensing of brokers, or case-by-case authorization of brokered deals.
Other ATT provisions with extraterritorial implications include:
- Article 2(2) defining transfers to include export, import, transit, trans-shipment and brokering, pulling intermediary activities into scope.
- Article 7 export assessments, which require evaluating downstream risk of diversion, human rights violations, or breaches of international humanitarian law — necessarily a judgement about conduct beyond the exporting state.
- Article 11 (Diversion), obliging states to cooperate to prevent arms reaching unauthorised end-users abroad.
In practice, extraterritorial implementation varies widely. The EU Common Position 2008/944/CFSP and member-state brokering laws (e.g., Germany's Außenwirtschaftsgesetz, the UK's Export Control Order 2008) reach nationals operating overseas. The United States, which signed but has unsigned the ATT (the Trump administration announced withdrawal of the signature in April 2019), regulates brokering extraterritorially under the Arms Export Control Act and ITAR Part 129.
For researchers, the key analytical point is that extraterritorial controls are the ATT's main answer to the "shadow broker" problem documented in cases like the Viktor Bout network — but enforcement depends entirely on domestic legislation and prosecutorial will.
Example
In 2013, the UK prosecuted arms broker Gary Hyde under the Export Control Act 2002 for arranging a shipment of 80,000 AK-47-type rifles and other weapons from China to Nigeria in 2007 without a UK trade control licence — an extraterritorial brokering offence of the kind Article 10 of the ATT asks states parties to criminalise.
Frequently asked questions
Not explicitly. Article 10 requires states to 'regulate' brokering under their jurisdiction but leaves the definition of jurisdiction and the choice of enforcement tools — licensing, registration, or criminal sanctions — to each state party.
