The rule should be:"We don't negotiate with narcissists."

Is this true? Do you have an example?

"Beijing granted Ivanka trademarks, Qatar invested in one of Jared’s office towers, and Ukraine, with Slavic candor, simply wired half a million dollars to the President’s personal lawyer Michael Cohen."

From the Maclean's article in the top comment.

HN shouldn't regurgitate political hit pieces. Ivanka Trump's business has trademarks registered throughout the world... it is no great honor to get a trademark registered in China.

Qatar did not invest in Kushener's office tower.

And, a payment to Cohen by Ukrsine has been denied. (And, in any case, would be perfectly legal so long as the appropriate lobbying paperwork was filled out.)

No, I don't have "an" example, but there are a many if you bother to look.

How about this one? https://www.vox.com/policy-and-politics/2018/5/15/17355202/t...

"As I’ve pointed out before, the President can be successfully engaged, and countries like Ukraine, China, and Qatar have demonstrated this. When they want something from the United States, they skip the State Department, and even the White House staff. Instead of approaching their problem state-to-state, they go state-to-man. These countries focus on what Trump wants on a personal level – to enrich his family. So Beijing granted Ivanka trademarks, Qatar invested in one of Jared’s office towers, and Ukraine, with Slavic candor, simply wired half a million dollars to the President’s personal lawyer Michael Cohen."

Also China's loan for Trumps indonesian project and the rumoured Russian financing/laundering and Trumps positive behaviour toward Russia/Putin.

While possibly coincidence, there certainly seems correlation between countries that are treated favourable and helping Trump family business interests.

It's hard for me to believe this is being asked in good faith

i did ask it in good faith. Sorry whole world doesn't follow american politics closely, believe it or not.
