Jan.21 (China Defense Mashup Report) -- The Chinese peacekeeping engineering battalion to Lebanon is the first detachment implementing minesweeping and boundary marker setting operations along the "blue line". Since September 2007, it has successfully opened 25 safety passages with a total length of over 4，000 m along the "blue line", destroyed more than 600 landmines and unexploded explosives and set up 36 boundary markers. Such as "cross detecting" and "human-machine combined minesweeping" methods have been included in the standard operational procedure of the United Nations.

In March 2006, China dispatched the first batch of peacekeeping troops to Lebanon. On July 25, 2006, the Israeli Air Force raided the Khiyam observation sentry post of the UN peacekeeping troops in Lebanon, leaving four UN observers, including Chinese military observer Du Zhaoyu, killed to our great sorrow in the accident. Du Zhaoyu became the 8th Chinese serviceman who laid down his life in UN peacekeeping operations.
