Shanghai - China's politically sensitive trade surplus expanded to $22.27bn in June, rising sharply from the previous month as the value of exports hit a record high, government data showed Sunday.
The trade surplus - a major point of tension for China's key trade partners, the United States and Europe -- outstripped May's $13.05bn surplus and an economists' forecast for $14.3bn.
"A monthly wider trade surplus due to lower global prices is understandable, and there is nothing to worry about," HSBC economist Qu Hongbin told Dow Jones Newswires.
Export growth slowed 17.9% year-on-year to $161.98bn - still at a record high for a single month based on previous data, the General Administration of Customs said in a statement.
Imports rose at a slower-than-expected 19.3% on-year to $139.71bn.
A Dow Jones Newswires survey of 14 economists had predicted a 19.2% rise in exports from a year earlier and June imports to expand 26.8% on-year.
For the first six months of the year, China's trade surplus fell 18.2% compared to the first half of 2010 to $44.93bn, the customs agency said.
Total foreign trade value topped $1.7 trillion in the first half of 2011, rising 25.8% on-year. Exports rose 24 percent to to $874.3bn. Imports climbed 27.6% to $829.37bn.
June's slowing exports could help ease concerns that China's currency is being kept artificially low handing it an unfair trade advantage.
China's boon from low export prices had been hurt by yuan appreciation and higher domestic costs, Zheng Yuesheng, director of the customs agency's statistics department told reporters in Beijing on Sunday.
He warned China's trade growth faced increased pressure from a "slow global economic recovery full of uncertainties," the lingering euro zone debt crisis and the unstable political situation in the Middle East and north Africa.
March's earthquake in Japan also set back trade between the two countries, Zheng said.
Analysts have played down concerns of a potential hard landing for the Asian powerhouse amid persistent government efforts to stem credit inflows and tame inflation, which hovers above 5%.
Growth in China's manufacturing sector almost stalled in June and year-on-year auto sales have fallen for two straight months as the government fights to dampen inflation.
China said on Saturday its inflation rate accelerated in June to the highest level in three years, as the government struggles to rein in soaring food costs.
The country's consumer price index rose 6.45 in June, the National Bureau of Statistics said in a statement, the highest level since June 2008 when the inflation rate reached 7.1%.
The government has said it expects price pressures to ease in the second half.
Some analysts are concerned Beijing might go too far in tightening monetary policy and trigger a sharp slowdown in the world's second largest economy -- which could have dire consequences for the world.
