Chinese and Italian police officers patrol the Wangfujing shopping area in Beijing on Monday. The joint patrol, the third such exercise between Chinese and Italian police in China, will last until July 5 in four cities: Beijing, Shanghai, Chongqing and Guangzhou. The joint patrol is reciprocal. Since May 2016, China has sent three groups of police officers to patrol streets in Italy. Italian officers were first invited to jointly patrol Beijing and Shanghai in April 2017. Xinhua
