(Adds background) LAGOS, July 5 (Reuters) - Nigeria's main militant group said on Sunday it had attacked a Royal Dutch Shell (RDSa.L) oil facility in the Niger Delta, its third such strike since President Umaru Yar'Adua made an amnesty offer last month. Germany's Merkel wants something of the same sort but it isfar from clear, officials say, that the gathering will reachanything amounting to a definitive decision on the charter theItalians calls the Lecce Framework.(With reporting by Reuters reporters worldwide; editing bySimon Jessop) Currencies Bonds China Russia Brazil Italy Japan. Marco Annunziata, economist at UniCredit bank, feels Beijingmay want the issue discussed in Italy but will not push to hard. "FX markets will of course wonder till the last minutewhether the BRICs or China alone will mount a serious challengeto the dollar, but are bound to be disappointed," he said.

In L'Aquila, Italy is also pressing leaders to back a globalcharter for business and finance, a sprawling compendium of bestpractices in labour, taxation, investment and myriad otherdomains where international organisations have producedthousands of mostly voluntary guidelines over the decades. Bankers reckon China holds perhaps 70 percent of its $1.95trillion in official currency reserves in the dollar. Some diplomats and bankers suggest Zhou's primary aim was tohighlight attention on concern expressed by Premier Wen Jiabaoabout the safety of China's huge dollar holdings -- at risk ifU.S policy turns to greater tolerance of inflation. dollar as the globalcurrency," Canadian Finance Minister Jim Flaherty said onFriday.

Beijing, equally, has reason to move carefully, even if ZhouXiaochuan, head of the Chinese central bank, launched the debatelast March when he said the SDR, the International MonetaryFund's unit of account, might one day displace the dollar. "In the midst of what is still a significant globalrecession, it's important that we aim for stability, andstability has been based on the U.S. If China insisted on something being put into a statement,it would surely be with references worded obscurely enough to be"meaningless", one official who spoke to Reuters said. The dollar lost a cent versus the euro at one stage lastweek when Reuters reported sources as saying Beijing wanted thematter debated. One official, speaking anonymously, went as far as to sayChina might push for a reference to the matter in the publishedstatements from the meetings.

Other sources involved in preparation of the meetings saidBrazil and India backed Beijing's call for debate but there wasconsensus among the G8, at least, that nothing of significancecould or should materialise at this stage. The OECD says fiscal stimulus should notbe withdrawn at a pace that jeopardises recovery. The most delicate issue leaders will face in economic termsis probably China's push for alternatives to the dollar as theworld's reserve currency. According to informationgleaned from sources, Germany will push the issue but face stiffresistance to anything beyond vague commitment.

Japanese officials cited the OECD latest commentary as apointer to the potential tenor of the statements that would beissued by G8 leaders. Washington, London, Paris and Japan, to name just some, donot want to commit so hard and fast to such an "exit strategy",even if they agree to the principle. The tension may rise in L'Aquila though, if, as sources say,Germany's Merkel presses others leaders to say in very explicitterms that they are committed to reverse quickly out of all theheavy spending and debts they have run up once the recoverystarts. Budget deficits are forecast to rise six-fold in the OECDgroup of countries by 2010, from 2007 levels, to 8.8 percent ofGDP from 1.4 percent, the OECD's latest forecasts show.
