China cannot endlessly avoid fighting a war if it wants to protect its growing foreign interests from Western predators

What the West is doing in Venezuela matters to both Russia and China, but this is probably the first time that a Western "adventure" matters at least equally to both Russia and China. Past Western nation-destruction plots [Afghanistan, Iraq, Libya, Syria] mattered far more to Russia, because Russia is almost the only superpower out there today which keeps a check on West's global crimes, but this time it's Venezuela - and China is heavily invested in this South American nation. Investments that'll evaporate in the blink of an eye if China allows West to install its puppet Juan Guaido as Venezuela's head.

China can't escape the fact that even if it doesn't want to, it'll eventually have to fight a war against the West or against West's proxies, if China wants to protect its increasing international interests from unilateral takeover by Western wolves. Amidst the Western-plotted coup attempt in Venezuela, China's can't simply issue so-called strong statements from its Ministry of Foreign Affairs. It must back its words with hardcore military power - fly in a 5000 strong group of Chinese armymen to Venezuela to:

1. Protect Venezuelan borders from incursion by Western-backed militants and weapons.
2. Deliver food, medicines and other essential aid to ensure peace and social stability.
3. Defend the legitimate Maduro government from foreign-backed overthrow attempts.
4. Weaken the domestic and international position of West's puppet Guaido.
5. Demonstrate to the West and to the world that China will not allow America to swallow Venezuela.
6. Demonstrate to the West that China will henceforth defend its global interests militarily.

The overall point being that China will have to flex its muscles, otherwise it'll surely lose its global interests.
