If Trump rise again the tone, it is that some hard points have still not been resolved.

The message accidentally from the president of the United States has been published at a time when some thought finally a possible agreement between Americans and Chinese. The White House had itself recognized that the discussions could lead to meaningful results. And, last Thursday, an american delegation headed by the secretary of State for Trade, Robert Lighthizer, and his counterpart at Treasury, Steve Mnuchin, have made the trip to Beijing. The visit back a hundred chinese officials, including the vice-prime minister Liu He this week in Washington, augured, therefore, may be progress, or even an agreement.

If Donald Trump rise again the tone, it is that some hard points have still not been resolved. The subjects of respect of the intellectual property, access to the chinese market for american companies, or of public subsidies granted by Beijing to the chinese companies remain particularly difficult to treat.
