Firstly the SCMP reports on a disturbing new trend in Vietnam:

...a new gambling craze in Vietnam: fish fighting, which can pull in bets of more than US$100 a bout...The aquatic version of cock-fighting has been around Vietnam as a folk game for decades. But only recently has it attracted high rollers...

The battles themselves are simple. Most punters buy their fish at the venue, for anywhere from US$1 to $3, though some of the more serious enthusiasts breed their own at home. The fish are typically small aquarium fish of undetermined species...varying colours are the key distinction for the casual buyer.

The selected fighters are placed in a bottle of water, which is then given a good shake, and the agitated fish usually start biting each other...In most bouts a winner is declared after a few minutes when one of the combatants stops attacking, though sometimes a particularly savage fish will kill its foe.

More interestingly the CSM has an article asking Would China invade Taiwan? It presents both sides and potential ramifications, including looking at the economic and broader geopolitical aspects of an invasion. To be honest they could have saved some newsprint. The same to the question is yes. Still it's worth a quick read.
