SINGAPORE (Reuters) - As China's stock markets have lurched wildly, seeding dramatic falls across the world, some have drawn parallels with the global financial crisis of 2008 or the Asian version a decade earlier. They are weak comparisons.
The abrupt end of Japan's boom in the 1990s, complete with stock crash and property bust, offers the most striking similarities, and the most valuable lessons.
China's stocks ran up gains of 150 percent in about a year before the mid-June crash, supercharged by margin lending and ignoring the drumbeat of disappointing economic data.
That makes for facile comparisons with 2008, the most recent example of a credit-fuelled bubble.

But there was no trigger like U.S. authorities' shock decision to let Lehman Brothers, at the heart of the global banking system, collapse in 2008.
"If you look at the extremes in the equity market they are almost comparable with the Lehman days. In those days we had a trigger, a real event, something clearly defined," said Christian Lenk, rate strategist at DZ Bank in Frankfurt, on Tuesday.
"What we saw yesterday was ongoing fears about China ... but there was no trigger, so we see a bit of normalisation today."
And it was no surprise that China's stock bull run, like its property bubble a year earlier, came to an end, Japanese Finance Minister Taro Aso said this week.
The anatomy of the Asian financial crisis was also quite different, as hot money deserted a region with high foreign debt and trade deficits and currencies they couldn't support.
"There are few similarities to the Asian crisis in 1997 and 1998, which was driven more by large deficits in trade accounts," said John Vail, chief global strategist at Nikko Asset Management in New York.
"What we're seeing now is more of a rapid change in sentiment around the world," he said.
The comparisons between China now and Japan in the 1990s, however, are striking.
Like Japan then, China was trying to cool frothy property and equity markets.
Both economies were powered by massive investment, huge trade surpluses and overvalued currencies and were liberalising their financial sectors. China's share of the global economy now is roughly the same as Japan's was in 1990, about 12 percent.
AVOIDING JAPAN'S MISTAKES
Japan's real GDP growth averaged 5 percent in the run-up to the crash, while China's averaged 10 percent over the past decade.
Credit growth was explosive in both, and the market crashes were triggered in part by efforts to temper exuberance.
Policy response was stop-and-go in both cases, with China seesawing on IPO policies, market liquidity operations and its treatment of shadow banking loans.
Chinese policymakers fear falling into the trap of deflation and stagnation that has gripped Japan ever since.
"They aren't a single bit interested in Japan's successes. Their biggest interest is in Japan's mistakes," one China-based Japanese source in touch with Chinese regulators told Reuters in March.
"Japanese and Chinese economies do share many similarities, so I assume there is quite a lot to learn from our experiences."
Global investors will also see some threatening differences. Global growth is weak, and China accounts for two fifths of that. It also accounts for most of the growth of many multinationals.
As the largest consumer of commodities, its slowdown is hammering the price of fuel resources and metals, unleashing deflationary pressure across the world.
Japan's woes coincided with robust global growth and had fewer international consequences.
"Japan's collapse in the 90s was very much reflected into itself with just some knock-on effect into the rest of Asia," said Adam Slater, lead economist at UK-based Oxford Economics.
"The impact of China's slowdown will ... leave us in a very disappointing growth phase for the next year or two for the world as a whole."
Some important differences, and lessons learned from Japan's experience, will be welcome to global investors and Chinese policymakers alike.
China's stock market is much smaller relative to GDP than Japan's was - 40 percent versus 140 percent - so should have less economic impact. Per capita it is still a middle-income nation with only 55 percent urbanisation, so has plenty of scope for infrastructure spending to support the economy.
While Japan was slow to act - monetary easing came too little, too late, fiscal stimulus was withdrawn early - and its capital markets at the mercy of international flows, while China, with tight control of its capital account, has been proactive to a fault.
Its frequent monetary interventions and constant regulatory tinkering, whether in the stock or housing markets or in local government lending, are not always effective and sometimes counterproductive, but it rarely fiddles while Beijing burns.
