Now that tariffs have been imposed, negotiations have not started.  Instead, Trump seems determined to continue to escalate.  Rather than make movements towards resolving issues, he has now threatened to impose tariffs on every product imported from China—all $500 billion. Since China does not import an equivalent amount of goods from the United States, it cannot simply match tariff rate hikes to tariff rate hikes.  It will end up getting creative instead, assuming President Trump follows through on his threats and keeps ratcheting up tariffs on Chinese made goods. China could respond in many ways.  It can scrupulously enforce myriad domestic laws against American companies in China that are currently only weakly followed now.  It could much more rigorously check for compliance with every regulation, type of paperwork and so forth.
