BEIJING (Reuters) - China’s exports rose at the fastest pace since February 2018 in November, helped by strong global demand and as the factory recovery from the coronavirus in the world’s second-largest economy outpaced those of its major trading partners.Exports in November rose 21.1% from a year earlier, customs data showed on Monday, soundly beating analysts’ expectations for a 12.0% increase and quickening from an 11.4% increase in October. Imports rose 4.5% year-on-year in November, slower than October’s 4.7% growth, and underperforming expectations in a Reuters poll for a 6.1% increase, but still marking a third straight month of expansion. Analysts say improving domestic demand and higher commodity prices helped buoy the reading. That has led to a trade surplus for November of $75.42 billion, the largest since at least 1981 and wider than the poll’s forecast for a $53.5 billion surplus and $58.44 billion surplus in October. Booming sales of fridges, toasters and microwaves to households across the locked-down world have helped propel China’s manufacturing engine back to life, super-charging demand for key metals like steel, copper and aluminium, after a sharp slump early in the year. In another sign of brisk trade, China’s export surge and the low turnaround rate of containers from abroad have triggered a recent shortage of containers domestically, state media China Daily reported. A spate of early month economic data showed China’s economic recovery from the coronavirus pandemic has stepped up, with manufacturing surveys showing new export orders expanding at a faster pace for November. But some analysts cautioned that surging infections and fresh lockdowns in some key trading partners could dent demand for Chinese goods. A sharp appreciation of the yuan in recent months could also cloud the outlook for exporters. Some firms reported that a strong yuan squeezed profits and reduced export orders in November, the statistics bureau said this week. The yuan has booked six straight months of gains, its longest such winning streak since late 2014, and is trading at 2-1/2 year highs. While a Biden administration is expected to soften some of the diplomatic rhetoric seen in strained U.S.-China trade relations in recent years, there are no immediate signs the President-elect intends to unwind the punitive tariffs introduced under the Trump administration.
