Here is one way to explain the difference: The purpose of the meeting was to discuss the Magnitsky Law which is a US law imposing sanctions on 18-20 powerful Russians, including Russian officials named in the law. The sanctions were for Russia's corruption and treatment of Magnitsky (killed in Russian Prison) which also involved US Citizens investing in Russia (not Trump). In retaliation for the US Magnitsky Act, Russia passed a Russian law banning US adoptions of Russian babies and this was another item for the meeting. It would be a felony violation of US law if anyone at the meeting (all were non US Officials) discussed repealing the Magnitsky Act with agents or representatives of Russia. If the discussion involved repealing the Magnitsky Act it would be a felony violation of US law (a discussion is enough-- no agreement required). If information on Clinton and/or repeal of the Russian adoption law were even suggested, this is a more severe felony.
