The quote from James Clavell's "Noble House" highlights a historical perspective on China's defensive strategies. It suggests that China has a long-standing practice of extending its borders to create buffer zones against potential invaders. This history emphasizes the importance of territorial security in China's foreign policy and military strategy.

By underscoring this behavior, the quote also points to a broader understanding of how nations prioritize their sovereignty and geopolitical interests. The narrative suggests that China's proactive measures in its border regions are not just reactions but rather a calculated approach to safeguarding its national integrity against external threats.
