Treaty language and battlecruiser visits projected Pacific power

Several early-1920s diplomatic and regional events accompanied the quieter piracy record. The Nine-Power Treaty bound Britain, the United States, Japan, France, Italy, Belgium, the Netherlands, and Portugal to respect Chinese sovereignty. HMS Renown then carried the Prince of Wales through Singapore and onward to Japan. A royal tour was diplomatically friendly, but sending a battlecruiser also displayed what British naval power could bring to the region. A 1924 report similarly credited the concentration of ships with keeping Shanghai's foreign settlement untouched while fighting continued outside the city. The 1923 Great Kanto earthquake and a new Singapore-Malaya causeway added humanitarian and infrastructural context to the station's work. Together these events show that presence operated through treaties, ceremonial visits, relief, and bases as well as combat patrols.
