I believe that the cooperation between BOC and BOCOG will play an important role in ensuring a successful Olympics," Jiang added.     Germany's Volkswagen Group became the 2008 Olympics' automobilepartner last month.     The negotiations with potential Olympic partners in other fields are going smoothly and BOCOG is soon to unveil new partners,according to Jiang.     "We will continue to enthusiastically welcome the participationof foreign and domestic companies in the 2008 Olympics," he said.     BOC's deputy governor Hua Qingshan said BOC is honored to get involved in the 2008 Games, which shows the BOCOG and society's trust in them.     Reports said BOC is gearing up to gain stock market listing. BOC expressed in May its confidence in dropping its non-performingloan ratio to below 6 percent while raising its capital adequacy ratio to above 8 percent at the year end, a threshold for share sales.     China's State Council has poured a total of 45 billion US dollars, using the country's massive foreign currency reserve, into the BOC and China Construction Bank to help them raise capital in cash.
