Macron supported the open-door policy toward migrants from the Middle East and Africa pursued by Angela Merkel in Germany during the 2017 election campaign and promoted tolerance towards immigrants and Muslims. Macron expressed confidence in France's ability to absorb more immigrants and welcomed their arrival into Europe, asserting that the influx will have a positive economic impact. However, he later stated that France could "not hold everyone" and cited migration as a major concern of voters. New migration measures were introduced which toughened controls on asylum and fixed quotas for foreign workers.
