concession was to push APOC operations to the southwest of the country so as to make it possible for Persia to approach and lure other oil companies to develop oilfields on more equitable terms in areas not part of APOC's area of concession. Apart from demanding a more equitable share of the profits of the company, an issue that did not escape Teymourtash's attention was that the flow of transactions between APOC and its various subsidiaries deprived Iran of gaining an accurate and reliable appreciation of APOC's full profits. As such, he demanded that the company register itself in Tehran as well as London, and the exclusive rights of transportation of the oil be returned to the Iranian government.

However, while Teymourtash was led to believe that after four years of exhaustive and detailed discussions, he had succeeded in navigating
