So, by "in exchange" I don't mean quid-pro-quo China ships the U.S. 25 tons of Rare Earth metals because they're so impressed, I mean: what results are they expecting? Congress critters generally are looking for re-election and all the perks that come with long term tenure in a seat. Lobbyists are generally lookig for more pork from their critters. Contractor firms are looking for that pork as "contracts" they can overbill and under deliver for with impunity, etc. etc. There are international results expected as well, such as greater negotiating power to get more advantageous positions in agreements.
