Asian Tech Press (Dec 22) -- Tesla battery supplier Contemporary Amperex Technology Co Ltd (CATL) said on Wednesday it would not comment on rumors of building a factory in Poland.

Polish media reported on the same day that China's CATL might build a battery factory worth up to 2 billion euros in the country and had visited two sites for this purpose.

The Chinese battery maker visited sites at Jawor town in south-western Poland, and Stalowa Wola city in southeastern Poland. And it's said most of the factory's output will be shipped to Germany, where Tesla has a car factory.

In response, CATL said it would not make a comment. And Tesla-related sources said that this information was previously unknown and could not be confirmed at this time.
