U.S. President Donald Trump’s national security adviser said Wednesday that China should join the United States in trilateral arms talks with Russia.

The FBI is conducting roughly 1,000 investigations into suspected Chinese theft of U.S. intellectual property, with many expected to result in criminal charges against individuals and companies later in the year, U.S. law enforcement officials said Thursday.

The chief of the Federal Bureau of Investigation (FBI) says Russia is conducting an “information warfare” operation against the United States ahead of the 2020 presidential election, although he says he has not seen signs that Russian actors have attempted to breach election infrastructure.
