Four Divisions of the People's Liberation Army (PLA) of China with a total strength of about 50,000 troops and drawn from the Shenyang, Lanzhou, Jinan and Guangzhou military regions have embarked on a military exercise code-named Stride--2009 since August 11, 2009. The exercise is due to last for two months. The exercise has been projected by the Global Times (August 12, 2009) as China's largest ever, long-range military exercise.
Under this exercise, a Division of the Shenyang Military Region in the North-East will move to the Lanzhou Military Region in the North-West and a Division from the Lanzhou Region will move to the Shenyang Region. Similarly, two Divisions from the Jinan and the Guangzhou military Regions will exchange places. It is not clear from available details carried by the government and party controlled Chinese media whether the four Divisions will remain in their new place of deployment after the exercise or they will move back to their original place of deployment.
The objective of the exercise has been described as to test the ability of the Divisions to move rapidly from an area where they were raised and trained to an area to which they were not used. The objective is also to train the troops to fight anywhere, anytime and under any conditions. The exercise will also test the ability of the troops to deal with natural disasters in any part of the country . Another important aim is to test the new road, rail and air infrastructure raised by China in recent years and examine their capacity to support such large-scale movements without causing much inconvenience to the civilian population
The Lanzhou Military Region, one of the seven military regions of China, has under its jurisdiction Xinjiang, Qinghai, Gansu, Ningxia, and Shaanxi and the Ali area of northwest Tibet. The Shenyang Military region covers the Liaoning, Jilin, and Heilongiang provinces. It plays an important role in the security of Beijing as well as of the areas bordering on the Russian Far East and North Korea. The Jinan Military region covers the Shandong and Henan provinces. It is responsible for security in one of the most heavily populated and industrialised areas of China. The Guangzhou Military region covers the Guangdong, Guangxi, Hunan, Hebei and Hainan provinces. Inter alia, it is responsible for the security of Hong Kong and its Divisions are specially trained for possible military operations against Taiwan.
The three Regions not participating in the exercise are the Beijing, the Nanjing and the Chengdu Military Regions. The Beijing Military Region covers Beijing city, Tianjin city, the Hebei province, the Shanxi province, and the Inner Mongolia Autonomous Region. It is mainly responsible for defending China from Mongolia and Russia, and also provides security to Beijing. The Nanjing Military Region covers the Jiangsu, Zhejiang, Anhui, Fujian, and Jiangxi provinces. It is the principal Military Region responsible for operations against Taiwan in the event of a military conflct. Most of the missile units facing Taiwan are believed to be under its control. The Chengdu Military Region covers the Chongqing, Sichuan, Yunnan, Guizhou provinces and the Xizang/Tibet Autonomous Region. It is responsible for security in Tibet and for protecting the border regions with India, Nepal and Myanmar.
Thus while the Military Regions responsible for security in Tibet and Beijing and for military operations in Taiwan have not been disturbed during the exercise, the Military Region responsible for security in the recently-disturbed Xinjiang province gas been. One would have thought that the Chinese would be interested in testing the capacity of the newly-laid railway line to Lhasa and the road infrastructure in Tibet to support large-scale and rapid military movements. While the non-participation of the Nanjing Military Region has been seen by Chinese commentators as a confidence-building measure at a time when Beijing's relations with Taiwan are improving, no explanation has been forthcoming for the non-participation of the Chengdu Military Region. One is tempted to speculate whether this has been motivated by a desire not to cause undue alarm in India.
