Following the construction of the pipelines, the United States and the European Union proposed extending them by means of the proposed Trans-Caspian Oil Pipeline and the Trans-Caspian Gas Pipeline under the Caspian Sea to oil and gas fields on the eastern side (Kazakhstan and Turkmenistan sectors) of the Caspian Sea. In 2007, Russia signed agreements with Turkmenistan and Kazakhstan to connect their oil and gas fields to the Russian pipeline system effectively killing the undersea route. China has completed the Kazakhstan–China oil pipeline from the Kazakhstan oil fields to the Chinese Alashankou-Dushanzi Crude Oil Pipeline in China. China is also working on the Kazakhstan-China gas pipeline from the Kazakhstan gas fields to the Chinese West-East Gas Pipeline in China. Politics of oil nationalization Several countries have nationalised foreign-run oil businesses, often failing to compensate investors. Enrique Mosconi, the director of the Argentine state owned oil company Yacimientos Petrolíferos Fiscales (YPF, which was the first state owned oil company in the world, preceding the French Compagnie française des pétroles (CFP, French Company of Petroleums, today TotalEnergies), created in 1924 by the conservative Raymond Poincaré), advocated oil nationalization in the late 1920s among Latin American countries. The latter was achieved in Mexico during Lázaro Cárdenas's rule, with the Expropiación petrolera. Similarly Venezuela nationalized its oil industry in 1976. Politics of alternative fuels Vinod Khosla (a well known investor in IT firms and alternative energy) has argued that the political interests of environmental advocates, agricultural businesses, energy security advocates (such as ex-CIA director James Woolsey) and automakers, are all aligned for the increased production of ethanol. He pointed out that from 2003 to 2006, ethanol fuel in Brazil replaced 40% of its gasoline consumption while flex fuel vehicles went from 3% of car sales to 70%. Brazilian ethanol, which is produced using sugarcane, reduces greenhouse gases by 60-80% (20% for corn-produced ethanol). Khosla also said that ethanol was about 10% cheaper per given distance. There are currently ethanol subsidies in the United States but they are all blender's credits, meaning the oil refineries receive the subsidies rather than the farmers. There are indirect subsidies due to subsidising farmers to produce corn. Vinod says after one of his presentations in Davos, a senior Saudi oil official came up to him and threatened: "If biofuels start to take off, we will drop the price of oil." Since then, Vinod has come up with a new
