The policies pursued by the PCR are designed to maintain firm party control of the economy. In the formulation of Romania's economic development plans, the will of the party is predominant, and the degree of party control was augmented by the territorial and administrative reorganization of 1968 when economic commissions were established in each of the new counties to function under the direct supervision of the county PCR committees. These commissions made it possible for the party to have a direct hand in the local economic programs. During 1970 and 1971 party leaders noted that, whereas the annual production increase envisaged by the Five-Year Plan (1971-75) had been fulfilled for industry, that for agriculture fell far short. Ceausescu called for a renewal of intensive efforts in both industry and agriculture to meet the requirements of the people and to enable the country to achieve the true socialist state of development. National Minorities The integration of the major non-Romanian national groups into the life of the country has posed periodic problems for the PCR throughout the post-World War II era. Each of the communist constitutions guaranteed equal rights to the national minorities, rights that included the opportunity to use their own language and to have representation on local bodies of government. The Hungarian Autonomous Region had been created by the 1952 Constitution but was not continued under the 1968 territorial reorganization (see ch. 8; ch. 4). Party leaders explained the decision to abandon the concept of an autonomous region for the Hungarian population in terms of the need to integrate all of the minority groups fully into the Romanian political community. Spokesmen asserted that it is the policy of the PCR to respect the heritage of the various nationality groups and extend to them full political rights but at the same time to work to create conditions that will serve to unite all of the country under the leadership of the party. PCR leaders have feared the possibility of attempts by foreign elements to foster unrest among the country's larger minority groups. This was particularly true at the time of the Soviet-led invasion of Czechoslovakia, when Romanian leaders were apprehensive about the possibility of a similar intervention in their country. At that time PCR officials visited the areas where there were concentrations of Hungarian and German minorities, stressing national unity and equal rights for all national groups.
