Guangshan county is a friendly and cooperative county with foreign countries.

Guangshan County and Guangde County in Anhui Province are friendly and cooperative counties. Although Guangshan and Guangde are far away from Qianshan, they are related by blood and rooted in culture. Of the 500,000 people in Guangde County, more than half are from Guangshan County (including the areas under the jurisdiction of Xinxian County). From the day when Guangshan people set foot in Guangde, the folk exchanges between the two places, such as finding relatives and asking ancestors, have never stopped. Especially since April 2007, Guangde sent a delegation to Guangde for investigation, and in May 2008, Guangshan County also sent a delegation to Guangde for study and investigation. The door of political, economic and cultural exchanges between the two counties was officially opened, and the brotherhood between the two counties deepened rapidly, and the exchanges between the two counties also reached a new level.
