The Chinese military has boosted troop numbers along the border with North Korea since September amid mounting concerns about the health of Kim Jong-il, the North Korean leader, according to US officials.
Beijing has declined to discuss contingency plans with Washington, but the US officials said the Peoples’ Liberation Army has stationed more soldiers on the border to prepare for any possible influx of refugees due to instability, or regime change, in North Korea.
I doesn't sound like an invasion force is getting set. Just border defenses to keep a flood of refugees out.
This raises question, too. Does China have an agreement with South Korea and/or the United States to just stand aside and let North Korea sort out whatever chaos develops?
I can't imagine that China would take a chance of South Korea absorbing North Korea.
