If you don't recognise China, China won't recognise you. Have fun passing custom checks when you have "Lithuania" listed on your documents lol
And before people jump in with the usual ignorant nonsense of, ‘well they can just ship it via a third country’, they cannot. Not without committing fraud in any case.
Customs don’t care from where something is physically shipped from but rather where something was made. That’s why you cannot simply ship everything to Mexico and have it enter the US market tariff free under NAFTA.
Thus the significance of this change is that things made in Lithuania simply cannot be legally exported to China now, because you literally cannot select Lithuania as the country of origin for the customs declaration.
The only way Lithuanian products could (legally) enter the Chinese market now is if they were used as a (very small value) component for the finished products made elsewhere.
To illustrate just how bad a deal this is for Lithuania, while on the face of it, getting $600m from America in exchange for loosing $300m in trade might seem like a good deal, but if you factor in that the $300m is annual trade while the $600m handout from the Americans is a one-off, you might start to see the problem.
But I suspect the people in charge in Lithuania doesn’t care, because they are the ones getting the $600m while it’s ordinary hard working people who are loosing $300m every year.
This is how corruption with western characteristics works and how state capture happens.
