The European Union’s new, tougher approach to China is being shaped by French concerns that Beijing’s trade practices have started to pose a critical threat to core industries.

The government in Paris has taken a key role in driving the policy shift, according to people familiar with its thinking, calculating that inaction now would put the bloc’s economy on a path to long-term damage.

Officials speaking on condition of anonymity recalled the solar industry debacle a decade ago, when cheap imports from China gutted European production. One of the officials said Europe’s auto industry could potentially be vulnerable in the same way and so the EU faces a binary choice: Either it affirms its power or submits to China.
