Is there anything wrong with that?
Does Panama need to ask the US empire's permission as to who they include to manage the operations of their canal?
If the nations of Asia have the right to allow US imperial bases on their sovereign territory, Panama has the equal right to do allow any country to assist them in any capacity.
Just like how the US empire is arming the Republic of China as well as has garrisoned Japan, South Korea, and the Philippines to shut off Chinese shipping to the World when the US empire begins its next proxy war this time with China?
It's not about the moral question of right or wrong. it's about risk assessment.
If you play chess, there's no such thing as a wrong move. However there are stupid moves. If you want to expose your King and have to constantly defend it while your opponent relentlessly keeps you on the defensive, you're going to lose the game.
The Panama Canal is a vital resource which the US completed after the French failed, and we handed over complete control to Panama in 1977. We depend the canal to keep our goods moving between our east and the Pacific -- a vital passageway to allow those ships to reach Asia.
Think about all the goods we get from China and other countries in the Pacific Rim region. Many of those ships need to get to the US East Coast and Gulf Coast regions. The alternative would be to offload them in California and use trucks or railroads at additional cost to transport them over 2,000 miles. That, or waste time and fuel sailing around South America.
if anyone is against Trump's tariffs because they may increase the prices of imported goods, think about the wasted fossil fuels and transportation costs and the impact on prices that might have.
The average toll paid by cargo and passenger ships is $54,000. That's much cheaper than the alternatives -- unless someone else takes over and decides the US needs to pay $1M per ship.
