Beijing recently indicated that its response to more tariffs would include "qualitative" measures, which many analysts interpreted as creating regulatory hurdles or even stoking anti-US sentiment among consumers of United States products.
The tech sector, more broadly, will suffer from tariffs due to the nature and complexity of the worldwide supply chain that it relies on.
"While the trade conflict between the USA and China has had a limited impact so far, we can't rule out the possibility of a slowdown in the Chinese economy and a contraction in world trade should conflict grow and spread into the global market", Finance Minister Kim Dong-yeon said at a government meeting.
"The latest list of $200 billion of products to be subject to tariffs against China doubles down on a reckless strategy that will boomerang back to harm USA families and workers".
