Several European leaders including France's Emmanuel Macron advocated using the EU's Anti-Coercion Instrument, a security and trade policy tool known as the "trade bazooka", to target the US in retaliation.[258][259][260][29][261] Under the not-previously-used instrument, the EU may adopt countermeasures, sometimes described as sanctions, including tariffs, restrictions on public procurement, and measures affecting trade and investment.[252][262] Bernd Lange, chair of the European Parliament Committee on International Trade, supported its activation.[263] By 21 January EU countries were described as being increasingly open to using the ACI against the US, with Germany stating it will ask the Commission to explore its use.[264]
