Some commodities continued on Friday to feel the pressure from the latest round of China jitters, overshadowing the brighter news of eurozone agreement on a new Greek debt deal.
HSBC data on Thursday saw the country's manufacturing sector shrinking output this month for the first time in a year, with an index reading at a 28-month low.
Tokyo's benchmark December rubber contract fell 1.1% to 380.70 yen a kilogramme.
In Indonesia, the top palm oil producer, the Indonesian Palm Oil Producers Association, Gapki, estimated domestic output in 2011 at 22.5m-23m tonnes.
Sure, that signalled a rise on last year's 21.6m tonnes but it was below the 24.0m tonnes forecast by Oil World earlier in the week, when the analysis group warned that "price pressure from palm oil is thus unlikely to be over yet".
And some speculation in Kuala Lumpur has raised questions too over an Oil World assertion that output in second-ranked Malaysia will be "very large" this month.
"Market players said that the weather is bringing bad yields, therefore production in July is down slightly," a trader in Kuala Lumpur told Reuters, the news agency.
As a further stimulus to palm prices, the Muslim festival of Ramadan looms, a period of high demand (after dark) for foods, while likely to slow output as workers take holidays.
Kuala Lumpur's benchmark October palm oil contract added 0.5% to 3,144 ringgit a tonne as of 07:40 GMT (08:40 UK time), taking its recovery from its July low above 4%.

However, the official CPC model shows all of the US baking in the eight-to-14 day timeframe, with "much above normal" temperatures forecast for the central and lower Plains, and lower Corn Belt.
OK, not all weather models agree, and some forecasters are sceptical.
"The eight-to-14 day is way too warm over the entire eastern half of the US," WxRisk.com said.
But it caused enough uncertainty to help corn rebound after two losing sessions, with the best-traded December lot up 0.7% at $6.77 ¾ a bushel, matching, but not beating this time, the near-term September lot, which gained 0.7% to $6.83 ¾ a bushel.
Not that the removal of this gap is off the agenda, to judge by the recent trend,
"It has been almost a year that September corn has traded with a premium to December corn, and that spread is getting closer to even money," Mike Mawdsley at Market 1 noted.
The uncertainty spread to
"Willingness on traders' parts to push this market from the short side ahead of the weekend maybe somewhat muted limiting a strong move lower to finish the week," Dave Lehl at Benson Quinn Commodities said.
"Ever-changing weather forecasts and broader markets will continue to push and pull the wheat market."
Still, Chicago wheat for September delivery added 0.6% to $6.81 ½ a bushel, with the higher protein, but less speculator-influenced, Kansas and Minneapolis peers making smaller gains.
