The central parts of the Eurasian continent have for  millennia been a crossroads of civilisations. The northern  areas have historically been dominated by equestrian  nomads, while the cultural developments in the southern  parts has revolved around the pivotal merchant cities  that emerged along the ancient trade routes – the Silk  Road – connecting China with Rome. With the current political borders the region may be  defined in somewhat different ways. Most definitions  include all of the five former Soviet republics in the area,  Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan and  Tajikistan. It is also possible – taking into account  historical and cultural commonalities as well as the  political and economic reality of today – to include  Afghanistan, Mongolia and adjacent provinces of China  and Russia. The western and northern provinces of China,  Tibet, Xinjiang and Inner Mongolia have strong linguistic  and cultural links to the populations of the former Soviet  republics of Central Asia, as do some of the southern  provinces of Russian Siberia. Parts of Iran, Pakistan and  India are sometimes also included in the definition. For centuries the region was shaped by Arabic, Mongolian, Chinese and later  on mostly Persian and Turkish influences. After the collapse of the Soviet Union the influenses from present day Turkey and Iran  have increased anew. The five countries which today comprise the core of the region had their borders drawn as republics within the Soviet Union in  the 1920s. The division was made along ethnic lines, based on the group considered dominant in each area, and every republic  was bestowed with its own titular language. After the fall of the Soviet Union the political systems have, for the most part, kept  their authoritarian nature, and in recent years most of the countries have developed in an even more authoritarian direction.  Kyrgyzstan is in some ways an exception, having experienced two revolutions since independence. However, the country still has a long road ahead of it before stable democratic institutions can be formed. One major obstacle is the endemic corruption  prevalent in the Central Asian states.  The period since independence has been a time of national identity formation, as a conscious attempt to create strong and  independent nation-states. These ambitions unfortunately also contributed to increased tensions and competition between the  countries to the economic disadvantage of several of them. The infrastructure - transport routes  as well as energy systems -  were largely constructed at a time when the countries were part of the common Soviet economy. Today important transit routes  and transports are frequently being cut off due to disagreements between the countries. So far only Kazakhstan has had a  consistently favourable economic development, built on substantial oil and gas income assisted by economic reform.  Turkmenistan also has large gas deposits, but so far there are few signs that revenues are being used in a way that stimulates the  economy or benefits the wider population. Other important export products are metals, cotton and in the case of Kazakhstan,  cereals. From a security aspect, the region experiences the tension between great power interests. Russia and China attempt to increase  their respective influence in the region, while they also cooperate on security policy stressing their common interest in regional  stability, notably as members of the Shanghai Cooperation Organisation (SCO). China’s strategy for developent of its western  regions, an important resource base and transport corridor, brings rapid economic and demographic changes. A major matter of  concern is of course developments in Afghanistan and the risk of conflict spreading to the neighbouring countries. Should, on the  other hand, Afghanistan stabilise, there will be strong incentives among the surrounding major powers (including India and  Pakistan) to strengthen commercial exchange and extend the regional infrastructure. There are therefore important reasons to  view Afghanistan as an integral part of Central Asia. The US, too, has important strategic interests in the region. Bases in  Kyrgyzstan and Uzbekistan are used for transports to the war effort, but there are more fundamental reasons making it likely that  the US will strive for continued presence in the region, irrespective of developments in Afghanistan, not least the ambitions of  Russia and of China in particular.  Continued economic development and increased regional cooperation could transform the countries of Central Asia from pawns in the great power game to increasingly important actors at the strategic core of Eurasia.
