Copper concentrate imports rose 0.1 percent year on year to a new record high of 1.78 million tonnes in November.
China'sexports grew at a faster-than-expected pace in November, data from the General Administration of Customs showed Friday. The surplus was forecast to fall to USD35.0 billion from about USD38.2 billion in October.
It was the fastest annual increase since March 2017.
Still, the world's largest exporter faces uncertainty.
In dollar terms, exports advanced 12.3 percent year-over-year in November, well above the 5.9 percent rise economists had forecast.
Exports are growing amid a global tech boom ahead of the holiday season, they said.
Tighter rules to rein in risks from a rapid build-up in debt and cut pollution have weighed on overall activity since the third quarter.
Some of China's northern provinces have ordered factories to throttle back or halt output to reduce notoriously thick winter smog.
Besides ramped-up efforts to reduce winter pollution, authorities unveiled fresh regulatory measures last month for the financial sector, clamping down on high-risk lending and halting some dubious infrastructure projects that would swell local governments' debt.
In volumes terms, imports of copper, crude oil, iron ore and coal all rose from a month earlier.
Exports stood at 380,000 tonnes, up 8.6 percent from 350,000 tonnes in October and flat on a year earlier.
The trade surplus totaled $40.21 billion in November versus the expected surplus of $35.0 billion.
While exports are contributing to China's economic growth once again, global investors have been more focused on its strong appetite for industrial commodities such as iron ore and coal, which is boosting resources prices worldwide.
