A leasehold territory ceded to France in 1898, Guangzhouwan was supposed to rival Hong Kong in terms of commercial and maritime development. However, the small territory soon proved difficult to access and unsuited to France’s ambitions. Although not completely insignificant, trade was modest and irregular, and the concession remained in the shadow of the neighbouring British colony. This article examines the outlook of French consuls based in Hong Kong, and consequently Guangzhouwan’s influence in regional affairs. It provides an opportunity to examine the conflicts of interest between the French ministries of Colonies and Foreign Affairs, which crystallised around the opium issue in particular.
