"The proportion of trade disputes between the EU and China is actually very small and both sides should obey WTO regulations when dealing with trade problems," Ederer said, adding that the Chinese-made products involved in anti-dumping or anti-subsidy cases make up less than 1 percent of China's exports to the EU.
Last year, Sino-EU trade decreased by 3.7 percent from 2011 to $546.04 billion, data from the General Administration of Customs show.
China's exports to the EU reached $333.99 billion in 2012, a decline of 6.2 percent year-on-year. That decrease contributed to the United States surpassing the EU that year to become China's largest export destination, receiving $351.79 billion worth of the country's exports, a figure up 8.4 percent year-on-year.
The EU decided to initiate an anti-dumping investigation into imported Chinese solar panels in September and an anti-subsidies investigation in November.
"Final rulings in those cases are to be released in the first half of the year," Ederer said.
Nearly 60 percent of China's solar exports went to the EU in 2011, Reuters reported, and Europe was home to 74 percent of global solar installations, it said.
Ederer also said the EU welcomes Chinese investments into both European financial and fixed assets this year.
