Yes, they have scored a few 'own goals'. The PRC has certainly shown a willingness to punish countries that don't behave in what they perceive as the correct way, the current 'economic warfare' with Australia is an example. Despite PRC denials, the 50 ships full of Australian coal sitting waiting to be unloaded would certainly help them over the winter given they have had to ration power. Industrial activity has had to be reduced, black outs have happened and there are some very cold folks in some of the Chinese provinces.

Somewhat ironically and despite the tensions, total Australian exports to China in December increased by $2.3bn (21%) compared with November, the Australian Bureau of Statistics reported on Monday. This was on the strength of Iron ore exports and some one off wheat sales.
I know the message to other small/medium powers is don’t be like Australia, be obedient, subservient and compliant, however they have misjudged the reaction here very badly, which probably is best described as give 'em the finger and find new markets.
