Export growth plunged to 2.9 per cent over a year earlier from the previous month's 11.6 per cent, customs data showed Monday. Imports were flat, down from October's 2.4 per cent growth.
The figures were in line with analysts' warnings that a trade rebound that began in August was unsustainable due to weak global demand amid Europe's debt problems and a slow U.S. recovery.
The trade weakness comes as stronger factory production and consumer spending show China is starting to emerge from its deepest economic downturn since the 2008 global crisis.
China's reliance on trade has declined as domestic consumption grows but export-driven manufacturing still employs millions of workers and any weakness raises the risk of job losses and unrest.
Global demand for China's goods is so weak that the government has said exports likely will contribute nothing to this year's overall economic growth.
The International Monetary Fund and others expect growth this year of below 8 per cent. That would be strong by the standards of struggling Western economies but China's weakest performance since the 1990s.
Economic growth fell to a three-and-a-half-year low of 7.4 per cent in the three months ended Sept. 30. It is rebounding in the current quarter but a recovery is likely to be gradual and too weak to drive a global rebound without improvement in Europe and the United States, analysts say.
The improvement comes as a new generation of Communist Party leaders who were installed at a congress last month are taking power.
Data on Sunday showed November factory output increased 10.1 per cent from a year earlier, up from the previous month's 9.6 per cent. Retail sales rose 14.9 per cent, up from October's 14.5 per cent.
The improved factory output "will likely draw the attention of observers as a clear sign of recovery," said Goldman Sachs economists Yu Song and Yin Zhang in a report.
November exports were $179.4 billion while imports were $159.8 billion, the General Administration of Customs reported. The country's global trade surplus widened by 35 per cent over a year earlier to $19.6 billion.
Beijing set a 10 per cent growth target for trade this year but it looks increasingly unlikely to meet that. Trade growth has fallen steadily and declined to 5.8 per cent in the 11 months through November.
The commerce minister, Chen Deming, warned last month Chinese exporters face "relatively grim" conditions in coming months and "many difficulties next year."
The government said last month it saw "steady economic growth," suggesting there was no need for further major stimulus following interest rate cuts and higher spending on public works construction and investment by state companies.
China's import weakness reflects the impact of government curbs on construction and industrial investment that have suppressed demand for foreign iron ore, copper and other raw materials.
Communist leaders want to shift the basis of economic growth to domestic consumption and services, a strategy that promises smaller but more sustainable gains.
It could reduce China's appetite for imports, hurting suppliers such as Australia, Brazil and some African economies, where Chinese spending has fueled an economic boom.
