SHANGHAI - Chinese mainland stocks were little changed on Wednesday morning, hovering near 20-month highs, thanks to rising investor confidence over the economic outlook even as regulators tap the brakes on excess credit.
A correction in banking stocks and sell-off in firms tapped into Apple Inc's supply chain were counteracted by strength in coal miners amid mainland's sweeping pollution crackdown.

UBS strategist Gao Ting said that although policy makers remained focused on reducing financial risks, "the recent strength of the RMB against the USD points to lower risk to domestic liquidity from capital outflow."
Indeed, the yuan's surge this year has helped increase foreign purchases of mainland equities. Net purchases of mainland A-shares via the "Stock Connect" scheme increased for five months in a row to 27 billion yuan in August, while foreign holdings under the Qualified Foreign Institutional Investor (QFII) scheme jumped 18 percent in the second quarter.
Shares of listed firms that engage in ethanol production surged, after state media reports that China plans nationwide use of ethanol in gasoline fuel by 2020, as Beijing intensifies its push to boost industrial demand for corn and clean up choking smog.
COFCO Biochemical Anhui jumped 6 percent, while Shandong Longlive Bio-Technology surged 10 percent.
Mainland's sweeping pollution crackdown also fuelled expectations of more shutdowns in coal mines, potentially pushing up coal prices and benefiting the country's biggest coal producers.
