EBay Inc. is evaluating acquisition targets in Japan and China, seeing Asia as key to growth. In the next five years, Asia is expected to be the fastest-growing region for the company, continuing a trend of the past five years, said Jay Lee, eBay’s managing director for the Asia-Pacific region. He said the company expects sales from the region to make up about a third of the company’s overall sales. He didn’t disclose the current proportion or give a time frame for the projection. Ebay’s second-quarter revenue rose 25% to $2.8 billion.
