維基解密網站引述美国外交密电指，搜尋引擎Google遭黑客入侵而退出中國的事件，是由中共中央政治局常委李長春和周永康一 手主導的。密电说李本人在Google输入自己的名字进行搜索时，发现一些「批评他的搜索链接」以及其子女的资料，令他非常震惊，也鉴于当时Google 国际版网站（Google.com）不受审查，还同时支持中文搜索，遂决意加强打压其中国业务，包括下令国营电信公司（中国电信、中国联通和中国移动）停 止与Google的业务往来，希望制止Google让过滤版网站Google.cn链接到其“非法的”国际版网站。密电也引述一名政治局官员的亲戚，声称 李长春曾“命令”攻击Google在美国的服务器。不过当《纽约时报》对此进行查证时发现，当时向美国披露消息的“官员亲戚”指，中宣部部长刘云山才是负责协调向Google施压的人。李长春与周永康曾在数次事件中，下达过批准指示，但没有直接资料显示两人是否涉及黑客入侵Gmail的案件。 根據維基解密2011年8月30日公佈一份美國駐北京大使館2009年5月18日發往華府電報，谷歌中國總裁李開復在電話中討論了中國政府施加的壓力，要求審查谷歌中文網。李開復斷言，問題的根源是中共中央政治局常委、宣傳部長李長春。谷歌領導層明確拒絕並「禮貌」告訴中國政府，李開復說，和他們對話的中方人員當時明顯不高興，說他們會把此消息報告給李長春。
Li Changchun (simplified Chinese: 李长春; traditional Chinese: 李長春; pinyin: Lǐ Chángchūn; born February 1944) was the propaganda chief of the Communist Party of China. He was the member of the 16th and 17th Politburo Standing Committee of the Communist Party of China, China's de facto top power organ, since 2002. He also served as Chairman of the CPC Central Guidance Commission for Building Spiritual Civilization, de facto Head of propaganda and media relations. Previously he had served in Liaoning, Henan and Guangdong.
Li Changchun was born in February 1944 in modern-day Dalian, Liaoning, then administered by the Empire of Japan as "Dairen", Kwantung Leased Territory. He joined the Communist Party of China in 1965 and graduated with a degree in electrical engineering from the Harbin Institute of Technology in 1966. In 1983, at age 39, he became the youngest mayor and Party secretary of a major city, of Shenyang, the capital of Liaoning. In 1987, he became governor of the province, a post he kept until 1990. As governor, mainland China's first expressway was built in the province, linking the cities of Shenyang and Dalian.
After Zhao Ziyang was purged from the party leadership in 1989 during the fallout from the Tiananmen Square protests that same year, Li was initially also thought to have been removed from the leadership because he was a supporter of Zhao. Li's appearance on state television weeks later showed that this was not the case. Li served briefly as the Party chief in the agricultural province of Henan in the 1990s. Jiang Zemin sent him to serve as Guangdong Party Secretary, where he cracked down on corruption to "put the house in order."
Li was promoted to the Politburo of the Communist Party of China in 1998, and made a member of its Standing Committee after General Secretary Jiang Zemin's retirement in 2002. There was a chance in 2002 that Li may have become premier, but they were damaged by some of the enemies of his political allies, Jiang Zemin and Li Peng. For example, Li was caught up in an "export rebate fraud" scandal uncovered in the Guangdong coastal city of Shantou in 2000, and criticized by Zhu Rongji for failing to detect the scam. Jiang nevertheless made sure to secure Li's promotion to the Politburo Standing Committee, though in 2002 he was "the sole member of the PBSC without a specific post in the cabinet of Party bureaucracy," and was initially simply charged with supervising the Party organs that deal with propaganda and ideology.
In October 2007, the Communist Party of China announced that Li would serve another term as Propaganda Chief.
There were high hopes among some in media circles that Li would signal a more liberal change from the strictures of former propaganda chief Ding Guangen. Li had made a major speech advocating that media stay "close to the public" and to real events, "instead of mechanically following Party directives." The hopes were short-lived however, though, after the Central Propaganda Department began closing newspapers, firing journalists, and would not allow foreign companies to produce content for TV stations in China. Many editors were punished and Li Changchun "started sounding and acting like another Ding Guangen."
In December 2010, one of the leaked United States diplomatic cables quoted a contact that claimed Li Changchun and fellow Politburo Standing Committee member Zhou Yongkang oversaw Beijing's cyber attack against Google. According to another leaked cable, Li was taken aback to discover that he could conduct Chinese-language searches on Google’s main international Web site. When Li typed his name into the search engine at google.com, he found "results critical of him."
James Fallows of The Atlantic later questioned the accuracy of the claim. He noted "[e]ven the author of the State Department cable is careful to say that the U.S. government cannot confirm the report".
