An insistence that Europe and Japan create a “level playing field” for trade by agreeing to give US exporters the same access to their markets as foreign companies receive in the United States. This push to expand US manufacturing exports is considered politically essential to fulfill President Bill Clinton' s campaign promise of more“high-wage, high-skill" jobs for Americans.
A willingness to impose sanctions on major trading partners to reduce trade barriers abroad, with less patience for drawn-out negotiations. Administration officials see little risk that this more aggressive policy could escalate into a full-fledged trade war that would shock the world' s fragile economies.Thus , the administration will not be deterred by complaints that it has moved to“protectionism”.
In what way could this push help "fulfill President Bill Clinton's campaign promise" ?

With the expansion of manufacturing exports, the US manufacturing industry would benefit.
