China is accusing the U.S. Congress of "groundless accusations" after the House passed a resolution calling on China to end alleged organ harvesting from prisoners of conscience.

The resolution passed Monday calls on the State Department to report annually to Congress on the implementation of an existing law barring visas to Chinese and other nationals engaged in coercive organ transplantation. The resolution also condemns persecution of the Falun Gong spiritual group which is outlawed in China.

Chinese Embassy spokesman Zhu Haiquan said Tuesday that the allegations of organ harvesting were fabricated. He said Falun Gong is anti-China and urged Congress to refrain from supporting it.

China said in 2015 it was stopping the transplantation of organs from executed prisoners. Activists contend that the practice continues and Falun Gong are targeted.
