Chinese-made fentanyl that is being trafficked in New York should be the main speaking point when US negotiators sit down with their Chinese counterparts this week, a top lawmaker said.

Sen. Chuck Schumer said China produces over 90 percent of the world’s fentanyl and its government does nothing to stop Chinese drug kingpins and manufacturers from cooking it up and illegally pushing it to Americans.

Fentanyl is a synthetic opioid up to 100 times stronger than heroin. Schumer said opioid overdoses in New York jumped from 2,166 in 2015 to 3,009 in 2016.

White House trade negotiators are expected to meet with Liu He, one of Chinese President Xi Jinping’s closest advisers, to iron out the straining economic trade ties between the countries.

Schumer said the health of Americans should be part of the negotiations.

“I am demanding negotiators impose real pressure on China to stop the export of fentanyl. As the scourge spreads and addiction grows, China’s authorities continue to turn a blind eye,” he said.

“Negotiators must not leave the table without addressing the export of fentanyl. This issue must be a major priority because too many lives have been lost and too many others are at stake, especially here in New York.”

Schumer said the opioid crisis has become one of the country’s top economic challenges and treating the addiction cost $500 billion in 2015.
