That phrase is part of every sentence the Turd utters these days. But he never says what's unfair about it. Is any of our trade with other countries compulsory? Don't we, companies or the government, have to ability to refuse any unfair deals?
If they charge too much, we don't buy it. If they don't want to pay the price we charge, we don't sell it to them. The only way that simple arrangement could be "unfair" is if either party was compelled to buy from or sell to the other. But that doesn't happen with or to us.
Furthermore, we and our trading partners have every right to NOT sell or to restrict the amount sold of whatever we export--just as we can choose to limit or ban the import of commodities. That's a voluntary decision either way. Nothing "unfair" about it. You don't want to buy, you don't. You don't want to sell, you don't.
The Turd has never explained what's "unfair" about trade...because he can't. (I know our resident MAGAholes will try...and I need a good laugh.)
