On this day, 32 years ago, September 4, 1993 (July 18, 1993 in the lunar calendar), the truth of the "Yinhe" incident was revealed. Sha Zukang talks about the Yinhe incident. At 1 p.m. on September 4, 1993, Sha Zukang, a representative of the China government and head of the Chinese inspection team, announced in Dammam, Saudi Arabia that it has been ascertained that the China cargo ship "Yinhe" did not contain thiodiglycol and thionyl chloride. The "Inspection Report" on the China cargo ship "Yinhe" announced by Sha Zukang, head of the Chinese inspection team, stated that Saudi government representatives, in the presence of China government representatives, inspected the cargo carried by the China cargo ship "Yinhe" at Dammam Port in Saudi Arabia from August 26 to September 4, 1993. The U.S. government sent technical experts to participate in the inspection as Saudi Arabia's advisers. The "inspection report" signed by representatives of the China government and the Saudi government as well as U.S. technical advisers said: "Through a thorough inspection of all containers on the ship 'Yinhe', the results showed that the ship did not contain two types of chemicals, thiodiglycol and thionyl chloride." Since July 23, the United States has repeatedly negotiated with China on the grounds of obtaining intelligence, groundlessly accusing China's "Galaxy" cargo ship of carrying chemical weapons precursors diethylene glycol and thionyl chloride to Iran, and took extraordinary actions such as tracking warships to warships and taking photos of military aircraft against the "Galaxy" cargo ship on the high seas to interfere with the normal navigation of the cargo ship. The United States also spread false intelligence to the countries where the "Galaxy" cargo ship is expected to call at, and based on this, required these countries to prevent the "Galaxy" cargo ship from entering the port and unloading goods as planned. The "Galaxy" cargo ship was forced to drift on the high seas for 24 days, was forced to change its route and delay unloading, causing serious economic losses to China and threatening the safety of the Chinese ship and its personnel.
