"will... get smart"?
China has been moving production around the world for years. Follow various EU, US and WTO moves to make product more competitive from developing countries and you'll follow Chinese garment factories. If Bulubula gets a ten year pass on duty, China will open a pajama factory a hat works and a shoe company within months. When the benefits expire, they pack up and move to the next opportunity. China has moved considerable manufacturing to Vietnam. They are in heavy negotiations with the Philippines, coincidentally one of Trump's favorite dictator wannabe regimes, but they pulled out of Philippine manufacturing two decades ago because of the corruption and the miserable work ethic.
