The US "disinvited" two countries this week, not only North Korea, but also China from the biannual naval exercises in Hawaii. Both "disinvitations" were a rescinding of a previous invitation after less than friendly saber rattling from the former invitee. Kim Jong Un's loud mouth is widely known, so the North Korean "disinvitation" came as no surprise.
China, specifically, has been pressuring African countries to "dis-recognize" Taiwan in favor of Beijing policy. Additionally, China has been pressuring US companies to follow otherwise unrecognized Chinese maps placing Taiwan under China's political sovereignty, as well as companies from other countries—which Taiwan is not currently under the control of. China sees the request as part of a grand goal of "reunification" and a nostalgic return to the rhapsodic geographical past as the keystone of a socioeconomic strengthening strategy.
The problem from the Western corporate perspective is with the dictionary, not with ideology. China's government does not decide the laws on Taiwan's island currently, not in any way. So, listing Taiwan "under" China would create confusion for Western tourists. But, China is run by Communists who believe that logistics are to be dictated, not recognized. In the land of Communist-Chinese, if tourists would be confused, the solution is to simply make a new law this afternoon outlawing tourists who are confused. So, Beijing doesn't believe the West has any legitimate problem with the policy, but that Western companies are only trying to spite Beijing.
Washington, however, does view the problem as ideological. It would be wrong for Washington to dictate the organizational nomenclature of the Bank of China or Sky News or Spotify. So would be any reciprocal resemblance. Under Trump, Washington is enforcing that ideology globally.
Then, there was yet another snafu among China's man-made islands. The US can't stop making news in Taiwan. A Senator makes an "unexpected" visit. US weapons developers are planning to set up shop in Taiwan. The US and Taiwan have decided that they can't build Taiwanese submarines fast enough. And, the US has decided that Taiwan needs the absolutely best defense to respond to Chinese "saber rattling", not only asymmetric defense. All of this is remarkably irritating and "disrespectful" to China.
China hates few things more than being disrespected.
