In mid-September Chinese President Xi Jinping rounded out a 10-day tour of Central Asia that included state visits to Turkmenistan, Kazakhstan, Uzbekistan and Kyrgyzstan, as well the G-20 summit in St. Petersburg and the Shanghai Cooperation Organization summit in Bishkek. At each stop, the new president made hearty pledges of financial support and calls for further diplomatic, security and energy cooperation. In Turkmenistan, Xi inaugurated a natural gas field. In Kazakhstan, he agreed to invest $30 billion in energy and transportation projects. In Uzbekistan and Kyrgyzstan, he made similar promises to increase investment and cooperation in the coming years.

China

Xi’s tour can be examined as part of China’s struggle to reduce its exposure to security risks and supply disruptions off its coast by developing new overland transport routes for goods, energy and other natural resources. China’s eastern seaboard, and the maritime realm beyond it, have dominated Chinese political, economic and military planning in recent decades, and in many ways it will continue to do so for the foreseeable future. The coast will remain central to China’s role in the global economy, facilitating the flow of Chinese goods to overseas markets, as well as the imports of seaborne energy and raw materials relied upon heavily by coastal provinces to feed their oversized manufacturing bases.

In recent years, however, anxiety within the Chinese Communist Party over the security implications of the country’s dependence on coastal trade has taken many forms. China’s aggressive efforts to modernize its navy and expand energy, resource and infrastructure projects overseas are perhaps its most visible attempts to cope with the geopolitical implications of its economic and energy needs. Xi’s tour, along with several other recent events, has highlighted China’s enduring need to focus on westward development as well.

Establishing a ‘New Border’

Geographically, China consists of three shelves that radiate up and outward from east to west like the steps of an amphitheater. The first and second shelves essentially hover over the Han core, where more than 90 percent of China’s roughly 1.3 billion people live. Surrounded by plateaus, mountains, deserts and steppe, the core historically has been vulnerable to attack — whether from Mongolian horsemen riding down through the Central Eurasian plains, the Manchu descending from Eastern Siberia or the Japanese (in 1592 and again during World War II) through the Korean Peninsula and Manchuria.

As a result, the history of Han China’s engagement with the sparsely populated, inhospitable lands on its periphery is defined by cycles of incorporation — with these regions transformed into protective buffers — and dispersal, whenever the core has fragmented and lost control of the frontier.

In many ways, Xinjiang represents the outer edge in this pattern. It is far more remote than other traditional buffer regions such as Inner Mongolia and Manchuria. Urumqi, the provincial capital, is more than 3,100 kilometers (1,920 miles) from Beijing, while Kashgar, the westernmost Chinese city and historically a major Silk Road trading hub, is nearly 4,400 kilometers from the coast. Xinjiang has also played a less-prominent role in Chinese history than the other buffer regions. Over the past 2,500 years, the region has broken away from China repeatedly, and it was not fully incorporated into the Chinese empire until the 18th century, taking the name Xinjiang, or “New Border,” a century later. China’s conquest of Xinjiang under the Qing Dynasty (1644-1911) was in part a response to the rise of Russia as a Eurasian power during the same period. Prior to then, there had been little threat of invasion from Central Asia and hence little reason to formally annex all of Xinjiang.

Moreover, Xinjiang is largely a desert wasteland cleaved in two by the Tianshan Mountains. The majority of its 22 million inhabitants live clustered in one of three sub-regional cores: the Uighur-dominated Tarim Basin to the south (centered in Kashgar), the majority Han Chinese Junggar Basin to the north (home to Urumqi), and the smaller Ili River Valley wedged in between. Today, Xinjiang accounts for 17 percent of China’s total landmass — an area roughly half the size of India — but less than 2 percent of its population. The physical environment of the region is simply too harsh to support large populations (by Chinese standards), even with modern agricultural and industrial technologies.

Long before Xinjiang became a military buffer for China, narrow passageways such as Alashankou, the Dzungarian Gate and the Karakoram Pass along the region’s borders with modern-day Kazakhstan and Pakistan shaped its economic, cultural and political identity as a commercial gateway to high-end goods such as silk, jade, spices and precious gems. The importance of trade along the Silk Road ebbed and flowed with changes in the Chinese economy and those of its major trading partners, and it has never accounted for more than a fraction of the Chinese Empire’s total economic output. Nonetheless, Xinjiang has long been important as a conduit for facilitating the exchange of ideas and technologies between China and the rest of Eurasia.

Modern Day: Building Trans-Eurasian Ties

In a speech in Astana, the Kazakh capital, on Sept. 7, Xi framed his tour as an effort to create a “Silk Road Economic Belt” through Xinjiang and the Central Asian states it borders, as well as Uzbekistan and Turkmenistan. Talk of re-establishing the historical trade route was promptly echoed by national and regional leaders in Xinjiang, who emphasized the region’s unique role as a land bridge to South and Central Asia.

Indeed, Xinjiang’s history as a trade route and protective buffer is still shaping Beijing’s interests and policies in the region today, especially as the Party looks to expand overland energy and trade ties with Central Asia. For Beijing, the challenges and opportunities presented by Xinjiang are manifold: As an energy transport corridor and resource base, the province will be critical for efforts to industrialize the interior and reduce China’s exposure to possible supply disruptions in the South and East China seas. At the same time, Xinjiang’s remoteness and terrain, as well persistent security concerns about the region’s restive Uighur Muslim population, will constrain Beijing’s most ambitious visions of trans-Eurasian road, rail and pipeline systems.

Nonetheless, there are already an unprecedented number of cross-border projects under various stages of development. Many, such as a proposed agricultural free trade zone along the Xinjiang-Tajikistan border, are small and expected to have a limited long-term impact. Others, such as a long-discussed overland transport corridor linking Kashgar (which was made into a special economic zone in 2010 and has since emerged as a focal point for state-led investment in Xinjiang) with the Chinese-operated Port of Gwadar in Pakistan, could be much more geopolitically significantly, albeit while facing enormous logistical, political and security constraints in the near term.
