China regulator denies probing Xiaomi-invested firms

China's securities watchdog has denied rumours that regulators are probing Xiaomi-invested firms or restricting such firms' listing plans. "We hope market participants don't believe in or spread rumours and work together to safeguard a sound market environment," CSRC said in a statement. Xiaomi said it has launched a lawsuit in response to "fabricated and baseless rumours" online.
