China has denied a report issued yesterday stating that it had penetrated the U.S. electrical grid.

The report issued by the Wall Street Journal on Wednesday said Chinese, Russian and other cyber spies had intruded into the electrical grid, leaving behind software programs which could cause damage to the network if activated.

The intrusion doesn't exist at all,” said Chinese Foreign Ministry spokeswoman Jiang Yu at a press conference Wednesday, according to China’s state media Xinhua.

We hope that the concerned media will prudently deal with some groundless remarks, especially those concerning accusations against China.

The Journal report said the alleged intruders had also entered other key infrastructure networks, raising concerns about national security.

“The Chinese have attempted to map our infrastructure, such as the electrical grid, a senior intelligence official told the Journal.

“Over the past several years, we have seen cyberattacks against critical infrastructures abroad, and many of our own infrastructures are as vulnerable as their foreign counterparts,” Director of National Intelligence Dennis Bair told lawmakers

Most of the entries were made by spies from China and Russia, the Wall Street Journal said.

There's absolutely no substance in this story about China and Russia attacking the U.S. power grid, Yu added, according to Agence France Presse. I hope the relevant U.S. press can truthfully handle their reports, particularly about China.
