The announcement late yesterday comes as Beijing struggles to reduce a glut of goods in an array of industries and reverse an export decline that threatens to cause politically dangerous job losses.
Its efforts so far have prompted complaints by European and US steelmakers and others that it is violating free-trading pledges.
In its latest measures, the Cabinet promised more bank lending, an increase in tax rebates and support for export credit.
"The foreign trade situation is complicated and grim," said the Cabinet statement. "Promoting foreign trade to return to stability is important for economic stability and upgrading."

Beijing is trying to shrink bloated companies, many of them state-owned, in industries including steel, coal, glass, cement and aluminium in which supply exceeds demand. That has led to price-cutting wars and heavy losses.
Yesterday's announcement follows a Cabinet announcement last month promising to boost steel exports with bank loans and other support.
Britain's government faces pressure to act after Tata Steel cited low-cost Chinese competition when it announced plans in April to sell money-losing operations there that employ 20,000 people.
Elsewhere in Europe, steelworkers have protested in Brussels outside the European Union headquarters.
Also in April, China pushed back against its trading partners, announcing anti-dumping duties on steel from the European Union, Japan and South Korea.
Yesterday's announcement also said Beijing will support companies in setting up foreign distribution centers and other sales infrastructure and shifting some operations abroad.
Plans for other industries have yet to be announced.
