You raise a good point and logically makes perfect sense since President Trump has consistently identified China as the source of the fentanyl being smuggled into the country and as the main cause of the current opioid epidemic.
Technically speaking, there is a product called China Dust...
China Dust is a 50/50 blend of JIS Z8901 Class 8 Test Dust and naturally occurring Silicon Dioxide (SiO2).
China Dust is made per Laboratory Test Method BZ 106-01.

... and is used for testing filtration systems and filters associated with the textile industry.
As far as my comment about impregnation of $1 bills above, fentanyl would be an unlikely contaminate as a bio-weapon:
"Contrary to what has been reported in some media outlets, topical (or transdermal; via the skin) and inhalative exposure to fentanyl is extremely unlikely to cause intoxication or overdose (except in cases of prolonged exposure with very large quantities of fentanyl), and first responders such as paramedics and police officers are at minimal risk of fentanyl poisoning through accidental contact with intact skin.[83][84][85] A 2020 article from the Journal of Medical Toxicology stated that "the consensus of the scientific community remains that illness from unintentional exposures is extremely unlikely, because opioids are not efficiently absorbed through the skin and are unlikely to be carried in the air."

The Centers for Disease Control and Prevention describe the U.S. opioid epidemic to have arrived in three waves.[7]
The first wave, which marked the start of the epidemic, began in the 1990s due to the push towards using opioid medications for chronic pain management and the increased promotion by pharmaceutical companies for medical professionals to use their opioid medications.
The second wave of the opioid epidemic started around 2010 and is characterized by the rise in heroin use and overdose deaths
The third and most recent wave of the opioid epidemic began in 2013 and is ongoing. This wave coincides with the steep rise in overdose deaths that involved synthetic opioids, particularly illegally produced fentanyl.
The drug is usually manufactured in China, then shipped to Mexico, where it is processed and packaged, which is then smuggled into the US by drug cartels.[105] A large amount is also purchased online and shipped through the US Postal Service.[106] It can also be purchased directly from China, which has become a major manufacturer of various synthetic drugs illegal in the US.[107] AP reporters found multiple sellers in China willing to ship carfentanyl, an elephant tranquilizer that is so potent it has been considered a chemical weapon. The sellers also offered advice on how to evade screening by US authorities.[108] According to Assistant US Attorney, Matt Cronin:
"It is a fact that the People's Republic of China is the source for the vast majority of synthetic opioids that are flooding the streets of the United States and Western democracies. It is a fact that these synthetic opioids are responsible for the overwhelming increase in overdose deaths in the United States. It is a fact that if the People's Republic of China wanted to shut down the synthetic opioids industry, they could do so in a day."
From Trump's speech:
"But we are going to have the country set up properly, like it was before the COVID came in... before the China Dust came in."
Linguistically the statement can be parsed either way... linking COVID to China Dust, or separating the two, since "before" is undefined. Contextually, I tend to agree with you... he is referring to fentanyl.
Fentanyl is bad enough, but here, again, are the sentences that directly precede Assistant US Attorney Cronin's quote above:
"AP reporters found multiple sellers in China willing to ship carfentanyl, an elephant tranquilizer that is so potent it has been considered a chemical weapon. The sellers also offered advice on how to evade screening by US authorities."
