Agree. But NOW, is China still a weak and poor nation?Your explanation is one of the major causes! This matter is considered a classic issue often raised by some Chinese descents complained that mainland China could not help or even so helpless amidst the mass killings etc during the intense Cold War era... those folks could not understand the actual conditions of China at that time, and its strength relative to the adversaries esp. the nonexistent Chinese naval force back then.
But an even much more significant explanation concerning those periods is China was still WEAK AND POOR. Being WEAK & POOR with very limited resources incl. the available ships explained lots of things. Expecting a poor and weak nation to come over to overseas to help... well, there were some, but of course the efforts were naturally limited. WEAK & POOR explained everything! If any one wanna blame, blame it to the "Century of Humiliation", blame it why the minority ruler of Qing dynasty were not blind to ignore rejuvenation and industrialization thus became so weak and easy prey... with very severe consequences carried over centuries later...
One day if China has been operating at least four carrier fleets of class 003 or higher in full combat mode, see if such blatant massacre still happens. Forget not that most of such cases involved the dirty hands of the USA, thus China must always calculate the US strength around. If a nation is still weak and poor, how can it help others in oversea areas???
Asking UN peacekeeping show the weakness of the government, only a few governments in the world ask UN peacekeeping for their internal problems. And usually, many government officials/military are involved, so they won't ask UN.One particular case like the recent one in Solomon Island, how could one expect China to interfere militarily, or even sent civilian ships to help? It is Solomon govt obligation to provide safety to its people incl those Solomon citizens of Chinese descent; if the legitimate central govt were not capable then asked the UN help then UN Peacekeeping Force can be deployed... that's the right procedure, and in that situation China may help.
Are you suggesting they form a kind of "triad " ? Don't agree with your suggestion, sorryOne suggestion, the Chinese community there must organize themselves to protect their own interests; how can have a Chinatown without some organized power or association to protect itself? At least they can pay a group of mercenary/thugs to protect the venue from the gang violence, organized or not?
When a massacre happened, people only think of their lives, no need for delicious food, no need for luxury apartments, they only need their lives saved, and it matters in a blink of eye, so asking UN for help is almost useless.
