It was further provided that the products of the soil and industry of Colombia should be admitted to the canal zone subject only to such duty as would be payable on similar products of the United States under similar conditions, and Colombian mails were to have free passage through the canal zone on payment of such duties or charges as were laid on the mails of the United States.[261] These tripartite treaties were of course to stand or fall together. The United States and Panama promptly ratified the agreements to which they were parties, but Colombia rejected the arrangement with indignation.
