The defendants stole data concerning on 78 million persons from Anthem’s computer network, including names, health identification numbers, dates of birth, Social Security numbers, addresses, telephone numbers, email addresses, employment information and income data, the indictment said.

The news comes amid tense relations between Washington and Beijing. Apart from the ongoing trade dispute between the two countries, the United States has also voiced security concerns over China's high-tech giants Huawei and ZTE telecommunications corporations. Huawei seeks to participate in the development of 5G Internet networks abroad, however, Washington has pointed to the alleged ties between the Huawei CEO and the Chinese government, and claimed that the company might use its technology for spying, something the company categorically denies.
