According to this sceptical line of thinking, it will take Beijing a generation to make the yuan a fully convertible currency that can rub shoulders with the dollar and the euro.
But a more tantalising interpretation of events is that China is proceeding quite nicely in expanding the use of the yuan beyond its borders, underlining its determination to eventually wield more influence in global financial affairs.
What has got optimists excited is the extension on June 17 of a pilot programme permitting imports and exports to be settled in yuan, also known as the renminbi, rather than in dollars or other foreign currencies.
The scheme was widened to firms in 20 Chinese provinces, not just five southern cities, and to counterparties in all countries, not just in Hong Kong, Macau and Southeast Asia.
The experiment got off to a slow start last July but has picked up as procedures have bedded down. Total trade settled in yuan doubled between the end of March and the end of May to 44.6 billion yuan.
That remains a drop in the ocean. But if China stands by the promise it made on June 19 to make the yuan more flexible, the attraction for domestic companies of avoiding foreign exchange risks by invoicing in their home currency can only grow.
As for exporters to China, the consensus that the yuan is headed higher is a big incentive to hold renminbi.
"We expect more than half of China's total trade flows, primarily bilateral trade with emerging markets, to be settled in renminbi in the next three to five years," Qu Hongbin, chief China economist at HSBC in Hong Kong, concluded in a report.
More Choices
It gets more intriguing. Companies outside China will be wary of holding yuan unless they have somewhere to invest it. Putting the money on deposit in Hong Kong, the main conduit for yuan settlement, yields a pittance.
On cue, plans are afoot to broaden the range of renminbi investments available in the territory.
Hopewell Highway Infrastructure Ltd , a toll-road company, announced the first non-financial renminbi corporate bond issue in Hong Kong.
Yuan-denominated insurance policies are expected soon, and the authorities are drawing up plans to let brokerages take yuan deposits and invest them in the mainland capital markets.
The scheme, dubbed "mini-QFII", is a junior version of the Qualified Foreign Institutional Investor (QFII) program, under which selected overseas funds have been permitted to convert about $30 billion of foreign currency into yuan and invest it in China.
As always with financial liberalisation in China, the pace will be sensible, not stunning. Expect strict quotas on the scheme.
And not to be forgotten, China said last week it would make it easier for domestic firms to move money overseas for purposes unrelated to trade or investment.
"With a more flexible exchange rate regime we expect to see further liberalisation of the capital account, and less need for China to accumulate foreign exchange reserves over the medium term," said Jianguang Shen, an economist for Mizuho in Hong Kong.
This gets to the nub of the political motives at work.
Resentful of the "exorbitant privilege" the United States enjoys in issuing the leading reserve currency, China would prefer to build up claims on the rest of the world in yuan -- raising its profile in the process -- rather than in a dollar it distrusts.
Central bank governor Zhou Xiaochuan sketched out a long-term plan in March 2009 to supplant the dollar with a super-sovereign currency akin to the International Monetary Fund's Special Drawing Right.
The yuan, he implied, would be one of its constituents. The SDR, the IMF's unit of account, now comprises the dollar, euro, yen and sterling.
Many commentators called Zhou's vision naive. But with emerging markets going from strength to strength while rich countries dro
