Finally, changing political situations and increased cross-national cooperation have allowed international business to flourish. Countries of different political systems are more open than before to conducting international trade with each other. Governments are spending more resources on the improvement of infrastructure facilitating the transport of goods and resources. Furthermore, governments have realized the benefits of international cooperation. In particular, governments engage in international cooperation in order to gain reciprocal advantages, to attack problems jointly that one country acting alone cannot solve, and to deal with areas of concern that lie outside the territory of any nation.
