On Monday, CDT Chinese reposted a letter circulating on Weibo which purportedly shows singer Katy Perry’s pledge to behave harmoniously during a prospective Chinese tour. “Fruit Sister” has performed in China in the past, but occasionally stumbled on moral or political sensitivities there. The letter includes promises to “observe the laws and regulations in China, comply with the management of the regulators,” and not to “add or change any content without authorization,” “do or say anything religious or political,” or “participate in any activities that jeopardize China’s unity and integrity.”
