All of those countries put together don’t make much of dent in a $337 billion trade deficit with China.
It also makes a big difference what type of goods are causing the trade surplus and for how long.
Some of the biggest US exports are scrap paper, plastics, and metals — due to US environmental rules which make reprocessing them into useful products uneconomic in the US.
Coal is another big export that is declining in volume fairly quickly.
Some of those countries are exporting less oil and gas to US and buying more weapons, which is a new phenomenon.
Some of those countries, like Panama do not make anything, almost everything is imported. Oil, gas, cement, steel, construction materials, etc., even the “Panama hats” are all made in Ecuador. Panama is one of the largest maritime crossroads in the world, but they don’t even have a real shipyard for repairs, much less new building. The only legitimate thing Panama has going for it is the canal, which the US built and gave to them. Tourism is still small and mostly US tourist dollars. After the Canal and construction, semi-secret banking, money laundering, and illegal drug transit are Panama’s largest industries.
Some of those countries receive much more in US foreign aid than the amount of their trade deficits.
None of these trade surpluses are an excuse to tolerate the huge trade deficit with China.
