China has delayed financing a U.S. computer order.

Officials of Corporate Data Sciences, the Santa Clara-based company which last May received U.S. Commerce Department approval of a license to export $305 million in computers and related products to China, blamed the delays in part on Chinese concerns over foreign exchange deficits. The company is awaiting a $3-million letter of credit pertaining to planned exports of IBM computers and other products, as well as $5 million in funding related to the venture. So far, shipments worth $110,000 have been made under a separate letter of credit. Corporate Data said it has “no assurance as to when and if these conditions will be alleviated.”
