The paper focuses on the work of the Terra International Symposium of Sculpture in Kikinda and the way the state cultural policy regarding this cultural institution, its importance, functioning and its plans about sustainability and development. The first step was to analyse the cultural policy which needs to be implemented in order to enhance the country support to the culture (to its sustainability and development). Then the subject was considered by focusing on the current state of cultural policy in the Republic of Serbia. The level of the state budget income decides on whether a country will have long-term strategic plan on cultural policy to be implemented by authorities, or its tactical and operational decision making process will remain on an ad hoc basis. The latter represents the less favourable way, as the lack of strategic plan (even a short-term one) diminishes the chance for making a vision come true. The paper considers reasons behind the foundation and the activities of the Symposium, its basic engagements, mission, vision and strategic plan. It is concluded that in the most turbulent social circumstances Terra has managed to realize its goals and implement its adopted vision, mainly due to correct assessment of the state of play as well as of its own capacities. The high level of creativity in a global perspective proves the stability of Terra even in unfavourable conditions. Terra´s plan on further activities shows a clearly determined multidisciplinary approach consisting of creative, educational and museology and tourism related activities. Realization of a strategic plan in terms of multidisciplinary practice at this moment depends on Terra´s ability to obtain working space in a short time, by adapting of the venues that are already in its possession and also by including the cultural policy in the solution of this problem. The final part of the paper considers some possible actions of the state authorities that could be implemented in interdepartmental and intergovernmental cooperation on a municipal, provincial and state level. This intervention will enable Terra to achieve its sustainability and financial independence. A well-designed action plan will expand the Terra´s influence in the region, make better involvement of adopted disciplines in European and world trends. Once the country joins the European Union, further vision development will be possible with the assistance of European development funds.
