President Trump announced Feb. 1 new tariffs on China specifically because of the country’s lucrative fentanyl dollars. If Mr. Xi had lived up to his San Francisco pledge, there would be no tariff.

The Treasury Department issued a detailed narrative on how China’s pharmaceutical companies feed the Mexican cartels. These are not rogue companies. They could not possibly be in a long alliance with Mexican criminals without the Communist Party’s OK and direction.

Treasury stated that it has “designated 28 individuals and entities involved with the international proliferation of illicit drugs, including a China-based network responsible for the manufacturing and distribution of ton quantities of fentanyl.”

A “Chinese network” is pumping out horrible killer drugs. Who makes up this network? One syndicate leader is a Chinese industrialist.

The Xi Jinping fentanyl gaslighting is chronic. In December 2018, Mr. Xi made the exact same promise to none other than President Trump, who called it a “game changer.”

“The Sinaloa Cartel and Jalisco Cartel in Mexico, using chemicals largely sourced from China, are primarily responsible for the vast majority of the fentanyl that is being trafficked in communities across the United States,” the DEA said.

Does that sound like Mr. Xi kept his promise to Mr. Trump five years earlier? Mr. Trump acknowledged that his 2018 deal was a double cross.

“Chinese officials have failed to take the actions necessary to stem the flow of precursor chemicals to known criminal cartels and shut down money laundering by transnational criminal organizations,” the White House said.
