The national flag carrier is buying more Boeing 777 aircraft for its fleet. Negotiations are under way for finalising modalities of the deal that may be close to $1 billion.
The commitment period for payment may stretch over three years. It would be PIA's second major deal for 777 aircraft during the last few years.
Lambright counted various other areas for which Exim Bank intends to facilitate Pakistan's public and private sectors for import from the US.
These were locomotives for railways, agri appliances, power and housing sector machinery. He, however, did not give priority to big dams for financing, saying construction of big dams involves many complexities such as environmental hazards, displacement of huge number of people and damage to a large area of land.
Coming back on PIA deal, James Lambright said Exim Bank would follow previous pattern to finance PIA deal for Boeing aircraft.
The Exim Bank acting chief added he had a meeting with PIA Chairman Tariq Kirmani to discuss details of the deal.
According to him, the new deal is part of the PIA policy of continuously upgrading its fleet. He said: "We are working with the PIA for buying new airplanes for its fleet and look forward to work in the future as well."
He had also held meetings with the adviser to prime minister on revenue and finance, railways minister, agriculture, members of the government economic team and heads of Pakistani banks during his stay for wide-ranging discussions on various issues of interest.
He said Pakistan railways is interested in buying 75 US made locomotives which, he believed, were more efficient, reliable and fuel efficient than Chinese and Japanese made.
He sounded upbeat about Pakistan's economy. He did not see any serious fall-out of October 8 earthquake on the country's economy.
He said: "No doubt earthquake is a big blow to Pakistan but, I believe, it was fully capable of coping with the situation."
He said despite deadly earthquake and its aftermath, Pakistan's economy will keep on growing in coming years and this factor will maintain Pakistan as a promising destination for investment and trade.
James Lambright counted various factors that would help Pakistan maintain its economic growth in the future. Among these he listed reforms, more trade and exports during the last few years, sizeable foreign exchange reserves and improved balance of payment.
He said Exim Bank would play more active role in the future to facilitate public and private sector in trade with US companies.
