There's countless reasons why they could have called off a tariff war, not least of which is that Colombia has a trade deficit with the usa, which would make a tariff war a very dumb idea for the USA.
This is all just classic Trump:
Make some dumb threats.
Others explain to Trump how it will personally harm him somehow (otherwise he wouldn't care).
Cancel the threats and declare victory.
The other party shrugs, but keeps silent to avoid harming Trump's fragile ego.
Consort is not necessarily sexual, fe: The mayor was known to be consorting with known criminals. It's also not necessarily an illicit relationship: "queen consort" in the UK for example.
Paramour works for both male/female illicit sexual partners.
Personally I like "her/his poolboy" for a ladies'/man's male paramour, but that meaning is probably not going to be in a dictionary, though most people will get what is meant.
