I believe the standard approach for misuse of such logos is to treat them as counterfeit goods (e.g. fake Gucci bags) which has an established process of seizing the goods at customs or distributor's warehouses and often destroying them. There's no need to sue the overseas producer specifically, as any distributor or retailer are also liable; and in general there's no need to sue as a cease&desist (to the local reseller within the reach of any penalty if they don't comply) is generally sufficient.
