ICC, which was established in 1919, had as its primary objective facilitating the flow of international trade at a time when nationalism and protectionsim posed serious threats to the world trading system.

facilitating the flow of international trade at a time when nationalism and protectionsim posed serious threats to the world trading system为动名词短语作had的宾语；

as its primary objective为介词短语作宾语补足语。

由于宾语很长，故宾语后移至宾补之后的句末位置。

have sth as its primary objective. 以某事作为其首要目标。sth有动名词短语充当。
