Over the past seven-odd years, China has tremendously expanded its railway network, particularly through the development of high-speed rail (or HSR, defined in China as any railway with speeds exceeding 200 kilometers [about 125 miles] per hour). Most of the growth occurred during the tenure of former Minister of Railways Lin Zhijuan and has been achieved by upgrading existing lines rather than building new ones. During this period, China's domestic HSR coverage has reached 8,358 kilometers, the longest high-speed network in the world. Meanwhile, China's railway technology has become an increasingly important part of its foreign diplomacy, extending the country's regional influence as well as addressing its growing energy demands. On April 27, China and Myanmar signed a memorandum of understanding (MoU) for a joint railway construction project connecting the eastern Myanmar border town of Muse, the main gateway between Myanmar and China's Yunnan province and the starting point of the Sino-Myanmar oil and gas pipeline, to the western port city of Kyaukphyu in Myanmar's Rakhine state. The 61-kilometer Muse-to-Lashio line is the first scheduled phase of the project, all of which is slated for completion within three years. To be built parallel to the Sino-Myanmar pipeline, which began construction in June 2010, the railway will significantly enhance pipeline security and provide access to the sea from southwestern China. While not strictly an HSR line, the Sino-Myanmar railway is an integral part of China's vast international-railway expansion plan. Over the past year, overseas orders for equipment and technology from China's major railway company, China South Locomotive & Rolling Stock Corp., have more than doubled and now account for 10 percent of the company's overall sales, or about $800 million. Though China's railway expertise is based on technology introduced from other countries and the domestic industry has reached maturity only in the last three years, much of its technology is less expensive to produce and therefore strongly competitive. The central government staunchly supports exports of China's railway technology, often attaching attractive financing terms and other economic or political perquisites, particularly for less developed countries. Since 2010, Chinese railway technology has also seen a significant breakthrough into developed markets, including the United States and Europe. But the Sino-Myanmar railway represents Beijing's most ambitious railway project yet, designed to expand China's links to the outside world. And similar projects are on the drawing board. According to a source within the China Railway Tunnel Group with knowledge of the plans, China is currently planning three more HSR networks, all heading in different directions - Southeast Asia, Central Asia and Russia. The source says negotiations are under way with a number of countries and progress is being made. Beijing hopes to complete the three new networks by 2025. Most of the HSR in the domestic portions of the networks will be designed for both passenger and freight transport.

Another line will link Bangkok to the southern Thai-Malaysian border region near Padang Basar. Under a draft MoU, construction is slated to begin in 2011 and be completed in 2016. Meanwhile, Chinese companies are also bidding for an HSR project connecting the Malaysian capital Kuala Lumpur to Singapore. Once these missing links are in place, China's existing railway network will extend south to Malaysia and Singapore. The Southeast Asian railway network will significantly enhance the degree of interconnection among ASEAN countries and boost China's regional influence through greater trade and economic cooperation under the ASEAN-China free trade agreement. The Singapore link will give China more direct access to the Southeast Asian trade hub and a greater export market, bypassing the South China Sea and the Strait of Taiwan, while the Myanmar link, by creating an alternate access route for China to the Indian Ocean, will enable it to avoid heavy reliance on the Strait of Malacca. Strategically, the railway network could alleviate any pressure on China from the United States' re-engagement with Asia and, coupled with Beijing's "charm offensive," help contain India's influence in the region.
