The Yinhe incident (Chinese:银河号事件) was a claim made in 1993 by the United States government that the China-based regular container ship Yinhe (银河, "Milky Way") was carrying materials for chemical weapons to Iran. The United States Navy forced the Yinhe to stop in the international waters of the Indian Ocean for three weeks. The Chinese government subsequently agreed to have the ship searched in Saudi Arabia by a joint Saudi-U.S. team. The final inspection report, signed by U.S. government representatives, concluded that "the complete inspection of all the containers aboard the Yinhe showed conclusively [that the chemicals] were not among the ship's cargo". Even though the Chinese were proven innocent, the U.S. government refused to apologize "because the United States had acted in good faith on intelligence from a number of sources, all of which proved to be wrong."
