As he prepares to begin a three-day trip to France, Chinese President Xi Jinping said he is hoping to get France's cooperation "in the framework of the 'Belt and Road' initiative."

In a letter published in the Le Figaro newspaper, Xi called for more trade and investment between the two countries. He listed nuclear energy, aeronautics, space and agriculture as industries with potential for deeper ties.

"French investors are welcome to share the opportunities of development in China," Xi wrote. "I equally hope that Chinese companies can better succeed in France."
