Renej,
Chinese Government investments in US Treasuries is larger than any other country. No need to go to trade war, they just need to threaten to sell US Treasuries. That would do so much more damage than a retaliatory tariff.
News reports have already mentioned this. They call it the Chinese "Nuclear" option. No, has nothing to do with Nukes, but with US Treasuries they own.
What's the take away from this topic? Don't get into debt. You become an indentured servant to the debt holder. Be debt free, or if you are not, work towards doing so.
