Our actions cause China to react, and I can say the same on opposite way. Here is a brief summary. For further reading, read the included links to articles and Wikipedia if available, which also provides updates. You can also search the updated YouTube videos on these topics.
Quantum computing / transmission
We present computer information with 1 bit either on or off. Quantum theory suggests there is a third state. For simple illustration, a coin can be either head or tail, and the third state (superposition) is when it is standing.
China can transmit information between Beijing and Shanghai via a 1,300 mile fiber link and one Chinese city to Vienna via a satellite using quantum technology. The transmitted data is virtually impossible to hack.
IBM, Google and China are working on quantum computers that are supposed to be many times faster than today’s top computers. As of 2020, it may still take a few years for practical uses.
Actions and reactions. China found out that NSA were spying on them from the transmission network via Edward Snowden. They knew they had to find a better way. Most Chinese scientists learned this technology from the west. Trump wanted to ban the scholars from China on technology even they have contributed a lot to the research and finance in U.S. universities. China’s huge investment forces us to fund more on our research in science (about time!).

China’s GPS (BeiDou)
China has a decent system similar to our GPS. EU and Russia have one. BeiDou is better than the U.S.’s, but I bet they will leapfrog each other.
Actions. U.S. had several incidents to stop GPS coverage on China. China would be a big disadvantage without their own GPS during a military war between the two countries.

Carrier killer missiles, swarm drones and undetected submarines
They are supposed to be effective to down a carrier, but they have not been proven in actual wars. If the missile cannot be detected in the firing stage, it is hard to detect on its way towards the target as it changes its projectile. We may not feel the threat now, but who knows in their fast development?
In theory, it is hard to protect (and not economically feasible) from a swarm of drones with some carrying bombs. It may be a long way to be deployed in downing a carrier.
The technology of silent (harder to detect) submarine was most likely from U.S. or Russia.
Actions and reactions. We have sent fleets to South China Sea and Obama declared ‘return to the Pacific’. We are developing solutions to China’s new weapons.

China’s carriers
The first one is for training and was refitted from a Ukraine’s carrier. The second one is an improvement from the first one, but it is still old technology. The third one is a big improvement and should be ready in 2020 - 2021. The fourth one is nuclear-powered and it is in the design phase as of 2020.
Actions and reactions. China needs to protect the sea route supplying oil and materials. China is decades behind us in carriers, but the gap has been reduced.

Chip making
Chinese can design many products using chips, but they do not have advanced chip makers and depend many chips from us.
Actions and reactions. Trump banned Huawei and a few Chinese companies from buying U.S. chips and the chip makers if they have a specific percent of U.S. technology.
Banning ASML’s most advanced chip makers is a blow to China. China now concentrates their effort and resources on building chip makers. You cannot build a house without strong foundation.
The U.S. is losing big sales and profits from China. When China is ready to build their own advanced chip makers, the U.S. chip companies will be in permanent loss. This is why most if not all chip companies oppose Trump’s decision.

Newton is right that there is a reaction to every action even in politics; also there is an action to every reaction.
