Conservative ethnic Mennonites normally do not engage in missionary activities but look for a quiet and remote place where they can live according to their tradition.

[2] In the year 1986 a group of very conservative ethnic Mennonites from Capulin colony, close to the city of Nuevo Casas Grandes in the northern parts of Chihuahua, Mexico, came to Argentina and founded "La Nueva Esperanza" colony 40 kilometres from Guatraché, La Pampa.

A second colony of similar immigrants was founded near Pampa de los Guanacos, Santiago del Estero in 1995 by Mennonites from Durango, Mexico.

[8] In 2019, a group of Mennonites from Chihuahua and Canada, bought 8,038 hectares (19,860 acres) of land near Arizona, Gobernador Dupuy Department, San Luis, 296 kilometres (184 mi) from the state capital, which will be 180 families (about 1,000 people).

[14] Ethnic Mennonites in Argentina speak Plautdietsch in everyday life and use an old-fashioned Standard German in reading, writing and singing.

[3] By 2007, 1,300 people were surveyed in the town of Remecó, La Pampa, consisting of approximately 200 families, with an average of 8 to 12 children each.

As well, grow potatoes, radish, cucumber, pumpkin, onion, pepper, carrot, sunflower, lettuce, cabbage, and cilantro; they raise poultry, pigs and horses.

Through a civil partnership, they sell several products to the rest of Argentina, such as cheese, pasta with mozzarella, wheat, furniture, silos and other implements for agriculture.
