A larger political disagreement between the two groups regards illegal immigration. The majority of illegal Asian immigrants to France are from mainland China, specifically the Wenzhou region, with a smaller number from northern China. While Wenzhounese and Dongbei community groups favor granting residency to illegal Chinese immigrants already in France, Chinese from Indochina are strongly opposed to the idea and support the French government's deportation of illegal immigrants. Indochinese community leaders and French politicians have accused illegal mainland Chinese of money laundering. Legal migrants have also been accused of tax evasion and supporting illegal Chinese migrants. A number of illegal Wenzhounese have fled France to neighboring countries such as Italy through the passport-free Schengen Agreement.
