May be China and Japan are not interested to BD.
It's is not a matter of interest or caring or concern. Everyone human being is important.
For example, during the earthquake in Sichuan of 2008 China was happy that many nations extended a hand of friendship and help. Even those with evil ulterior motives, we must still accept their offer..... why you ask? Because for the people in need, how can we refuse?
Likewise, when India offers to "help" if any other person/nation 'objects' --- then they will be looked upon poorly. Because most people would know understand the complex intricacies. Now I am not saying India has bad ulterior motives, nor am I saying that everything China or Japan does is 100% altruistic.
The TRUTH is that everything should be FAIR and should BENEFIT EVERYONE. Some members here accuse others of "doing it for their own benefit". Sometimes that may be true, but most times it is not --- people do things
mostly for their own benefit but
also for the benefit of others.
Think about it like this. Say you have a best friend, who is there when you need them and thinks of you. Wouldn't it be
appropriate to reciprocate?! So, when
all individuals benefit, that is a good thing.
And another point, if someone regards me as their good friend or best friend, then is would not mind at all if they have
other friends. Why should I object?! I should be happy my friend is popular and his/her life is fulfilling. Likewise, we should be cautious but not be petty minded about such relationships.
