Chinese companies known to use US trade secrets stolen by hackers could face punishment in the US if Congress passes proposed legislation on the measure, Financial Times reported. The House Intelligence Committee is drafting the bill that may include visa restrictions for any entity, not just Chinese, that uses intellectual property pilfered from US. Concerns over cyber theft and attacks originating in China have escalated in recent months. The proposed legislation is seen as a way to strike against hackers without irking the Chinese government or damaging US-China trade relations. The bill could be introduced in April.
