BEIJING (Reuters) - China will continue an investigation into U.S. chip giant Nvidia ( NVDA ) after preliminary findings showed it had violated the country's anti-monopoly law, China's market regulator said on Monday in a statement.

Beijing's decision to extend an antitrust probe into Nvidia's ( NVDA ) acquisition of Israeli chip designer Mellanox Technologies - claiming the California-based company violated the terms of the Chinese market regulator's 2020 conditional approval of that deal - comes as the U.S. and China hold trade talks in Madrid.
