This is a good thing for the Chinese (Government).
For the last few decades, their foreign policy has revolved around this principle: NO FOREIGN INTERFERENCE.
Thus China's harsh responses toward foreigners when it is perceived that outsiders are trying to split them and Taiwan further apart; China views Taiwan as part of itself (it was for about 300 years).
China has been offering rhetoric roughly on the same themes, which is that the United States has illegally (mostly) interfered in other countries' politics (true). Vietnam. Afghanistan. Israel. Palestine. China. Iran. Iraq. Oman. Yemen. Honduras. El Salvador. Peru. Mexico. Canada.
Now that the leader of the armed forces of the United States has gone so brazen as to literally pick a faraway independent sovereign country's leader (+spouse) off and drop them in a domestic courthouse for their political base's entertainment, China's foreign policy directive justifies its own existence once again.
The kidnapping will serve to push every single country, except Israel and the UAE, toward China's orbit. A planned visit by a high-level Australian minister in just a few days' time is proof of that; this has not occurred since 2020.
The General Secretary need only wait, and the US will destroy its international stature all its own. No foreign interference needed. Which makes it just the more ironic in the context of their foreign policy.
