Oh, this is what I actually wrote my master's thesis on! In short, mostly no.

There was no traumatic reduction of socioeconomic complexity during the bronze-iron transition in China (in fact, it was very much the opposite) in contrast to areas such as Greece and Anatolia circa 1200 BC. However, the introduction and proliferation of iron-working technology did non-critically contribute to a destructive geopolitical feedback loop, so I guess there's a small morsel of parallelism in terms of violence.
