Some thoughts at the Diplomat on China’s submarine export efforts:
China is beginning to aggressively court the submarine export market. In the wake of successful deals with Thailand and Pakistan, China’s submarine-building industry is developing new types with an eye towards breaking into the global market.
Given how many submarines China has built over the past decade, interest in the export market is hardly surprising. Historically, Chinese submarines have been uncompetitive with either Soviet or Western models, but the increasing efficiency of Chinese shipbuilding, combined with improvements in Chinese technology, have narrowed the gap.
