Yinhe incident
The Yinhe incident (Chinese: 银河号事件) occurred in 1993 after the United States government received intelligence that the China-based container ship Yinhe (银河; 'Milky Way') was carrying chemical weapon materials to Iran. The United States Navy forced the surrounding Middle Eastern countries to refuse docking rights to the Yinhe, leaving it in the international waters of the Indian Ocean for twenty-four days.
