Paris might be acting contrary to the plans of the G20 against tax avoidance by multinationals but Alternatives Economiques favours the move:

“France is reinforcing the trend towards bilateral agreements. ... Just as the British have done, and the Italians too. The most important thing, however, is that Trump essentially wants to offer tax amnesty to the top US corporations, giving them an opportunity to bring their profits stored in offshore tax havens back home at lower rates of taxation. Once the money is back in the United States, it means that less is available for other countries to demand in taxes. Seen this way France is right not to hesitate too long, even if it is regrettable that the bilateral battles will weaken international efforts as a result.”
