The first option would be to progress de facto toward a two-speed EU without establishing further legal commitments. Eurozone countries, together with others willing to join the euro in the future (the “eurozone plus”), could simply decide to use the legal means already available to increase cooperation.
第一种选择是将现状改造为两速欧盟，而不进行进一步的法制建设。欧元区国家以及准备在未来加入欧元区的国家（“准欧元区国家”）可以选择利用现有法律途径加强合作。
