Their different approaches include financial warfare (subverting banking systems and stock markets), drug warfare (attacking the fabric of society by flooding it with illicit drugs), psychological and media warfare (manipulating perceptions to break down enemy will), international law warfare (blocking enemy actions using multinational organizations), resource warfare (seizing control of vital natural resources), even ecological warfare (creating man-made earthquakes or other natural disasters).
This isn't just loose talk. There are signs of this strategy being implemented. The anti-Japanese riots that swept China in April? That would be psychological warfare against a major Asian rival. The stage-managed protests in 1999, after the U.S. accidentally bombed the Chinese Embassy in Belgrade, fall into the same category.
