"First. Will in no way interfere with any treaty port or any vested interest within any so-called 'sphere of interest' or leased territory it may have in China.
"Second. That the Chinese treaty tariff of the time being shall apply to all merchandise landed or shipped to all such ports as are within said 'sphere of interest' …, no matter to what nationality it may belong, and that duties so leviable shall be collected by the Chinese Government.
"Third, that it will levy no higher harbor dues on vessels of another nationality frequenting any sport in such 'sphere' than shall be levied on vessels of its nationality, and no higher railroad charges over lines built, controlled, or operated within its 'sphere' on merchandise belonging to citizens or subjects of other nationalities transported through such 'sphere' than shall be levied on similar merchandise belonging to its own nationals transported over equal distances."
