China determined to steal A.I. crown from US
Trade war with US could be a tipping point for China

In the case of the Apple iPhone, this means that China's exports balance accounts for the full $500 iPhone value, when China adds only approximately $15 to $30 of the value to the phone. Most of the iPhone value accretes to Samsung in Korea ($150) and to Apple — the brand owner and engineer. This highlights how the normal accounting of trade flows is inherently distorted under the current trade-deficit estimates. So maybe the deck has only 25 not 52 cards.

The iPhone example also points to an area of weakness in the president's policy prescription: If the United States introduces tariffs on China's high-tech goods, U.S. companies and consumers could indirectly end up footing part of the bill.
