He said the rapidly growing wealth of Communist officials’ children and family members "is what the public is most dissatisfied about". According to a January, 2014 investigation by the International Consortium of Investigative Journalists more than a dozen family members of China's top political and military leaders are linked to offshore companies based in the British Virgin Islands. The report shows that the brother-in-law of China's current Paramount leader, Xi Jinping and the son-in-law of former premier Wen Jiabao are amongst those making use of offshore financial havens to avoid tax and transfer money overseas. The Golden Shield Project has blocked foreign news sites that have reported on the scandal. Among the targets of the anti-corruption campaign since 2012 are Yao Gang, Vice-Chairman at the China Securities Regulatory Commission (CSRC), China’s top security regulator. He was investigated by the Communist Party of China's anti-graft agency in November 2015, after a stock market rout rocked global markets. Opinion surveys of Party officials and Chinese citizens over recent years set identify corruption as one of the public's top concerns. Every year researchers at the Central Party School, the CPC organ that trains senior and midlevel officials, survey over 100 officials at the school. Between 1999 and 2004 respondents ranked corruption as either the most serious or second most serious social problem. Similarly, in late 2006 the State Council’s Development Research Center asked 4,586 business executives (87 percent in nonstate firms) to rate their local officials in terms of integrity. Almost one-quarter said that their local officials were “bad”; 12 percent said they were “very bad.” In a commercial environment, corruption may be prevalent because many employees are not loyal to their employers, seeing themselves as "free-agent entrepreneurs" first and foremost. They use their employers as a way to make money, both for themselves and for their "guanxi social-circle network." The imperative of maintaining this social circle of benefits is seen as a primary goal for many involved in corruption. Official corruptions are among the populace's greatest gripes against the regime. According to Yan Sun, "If the Party executes every official for corruption, it will overdo a little; but if the Party executes every other official for corruption, it cannot go wrong." In contemporary China, bribe taking has become so entrenched that one party secretary in a poor county received repeated death threats for rejecting over 600,000 Renminbi in bribes during his tenure. In 1994, in another area officially designated "impoverished," a delegation of the UN Food and Agriculture Organization arrived for a conference on development, but upon seeing rows of imported luxury cars outside the conference site asked the local officials "Are you really poor?"
