Yuri Gripas/ReutersChina officially issued a warning to George Soros: beware of going to "war on the renminbi." The message comes in a piece published in China's People's Daily, titled "Declaring war on China's currency? Ha ha." People's Daily is the Communist Party's mouthpiece. "Soros's war on the renminbi and the Hong Kong dollar cannot possibly succeed — about this there can be no doubt," the opinion piece by a commerce ministry researcher warned, according to the Financial Times. This warning comes at time when China's officials are trying hard to get everyone confident in the renminbi again.
