GLOBAL MARKETS-Asian shares pull away from 3-year highs but gain on week

* Spreadbetters see subdued opening for European shares * U.S. jobless claims data, record S&P close underpin sentiment * Yen unfazed by CPI figures in line with economists' estimates * German Ifo awaited after euro pulls out of 8-month trough By Lisa Twaronite TOKYO, July 25 (Reuters) - Asian shares pulled back from this week's three-year highs on Friday after a mostly flat day on Wall Street, though a fresh S&P closing record and upbeat U.S. employment data underpinned sentiment.

Financial spreadbetters expected Britain's FTSE 100 to open 20 to 21 points lower, or down 0.3 percent; Germany's DAX to open 19 to 20 points lower, or down 0.2 percent, and France's CAC 40 to open down 11 to 12 points, or 0.3 percent lower.

Overnight data from France and Germany showed business activity in those countries strengthened in both July and June. But risks to the euro zone economy from any tougher sanctions on Russia limited the euro's gains.

Investors also were awaiting the Ifo Institute's closely-watched business sentiment survey due later on Friday.

"The German Ifo current assessment index and expectations index are both expected to decline, which could weaken euro/dollar," said Marshall Gittler, global head of FX strategy at IronFX Global.

"The Ifo index is in contrast to Thursday's positive PMI figures, perhaps because the Ifo incorporates more recent data on the impact that sanctions on Russia are likely to have on the German economy," Gittler said in a note to clients.

A survey on Thursday from China showing factory activity expanded at its fastest in 18 months in July also continued to give cautious markets a lift.

MSCI's broadest index of Asia-Pacific shares outside Japan was down about 0.3 percent, though still on track for solid weekly gain of more than 1 percent. Hong Kong's benchmark index hovered around its highest in more than three years, set for its best week since May.

Japan's Nikkei stock average gained 1.1 percent to a six-month closing high, rising 1.6 percent for the week.

"The prospect for the global economy has not been too bad thanks to recently strong U.S. shares and China data, but we should not be overly optimistic," said Norihiro Fujito, senior investment strategist at Mitsubishi UFJ Morgan Stanley Securities in Tokyo.

Fujito said that long-only investors have stayed on the sidelines as geopolitical concerns in Gaza and Ukraine have curbed their appetite for risk. He also said that investors are waiting for more positive trading cues, after the International Monetary Fund cut its 2014 forecast for global economic growth.
