By Emma Thomasson LONDON (Reuters) – British online grocer Ocado sees Amazons push to sell more groceries as more of an opportunity than a threat, believing it will encourage big international retailers to look for partners to help them get set up in e-commerce. What Amazon is clearly doing is awakening the global grocers to the online challenge they are going to face and they are accelerating the opportunities for us as a platform partner provider, Ocado Chief Executive Tim Steiner said on Thursday. Amazon plans to expand its Fresh grocery business within the United States this year and is reported to be considering launching in Germany, its second biggest market, prompting big retailers in the country to seek to set up online operations. Ocado expects to strike partnerships with retailers outside its home market Britain like its 200 million pounds deal with Morrisons, Britains No. 4 supermarket group, to provide its online grocery operation.
