In the afternoon of March 6, the two sides, under intense Chinese pressure, signed a “Preliminary Convention,” wherein the French recognized the “Republic of Vietnam” as a “free state” (état libre) within the Indochinese Federation and French Union; the Vietnamese agreed to welcome twenty-five thousand French troops for five years to relieve departing Chinese forces; and France in turn agreed to accept the results of a future popular referendum on the issue of unifying the three regions.
