In this Sunday, May 11, 2014 photo released by Hong, Chinese police with shields stand guard near the toll gate of a highway during a protest against the construction of a waste incinerator in Yuhang district, Hangzhou in China's Zhejiang province. Government pledges to seek public approval for a planned waste incinerator in eastern China failed to appease the project's neighbors Monday, May 12, 2014 after thousands of them, concerned over potential health hazards, blocked the highway and clashed with police in a bid to stop the construction.
