The French meanwhile impose a treaty of protectorate on Annam in 1884.

This treaty implies a French interest going beyond exploratory involvement in the affairs of Laos.

In June 1885, the French consul general in Bangkok notifies the Siamese government that a vice consulate will be established in Loang Prabang under the terms of a most-favored-nation clause contained in a Franco-Siamese treaty of 1856.

A new Franco-Siamese convention of May 1886 acknowledges the role of Siamese officials in Laos for the conduct of administrative matters but avoids implying French recognition of Siamese claims to sovereignty here.
