If all proceeds as planned, the world’s biggest animal cloning center will open next year in the northeastern Chinese port city of Tianjin, taking factory farming to a new level.

The center, being built by Boyalife Group, a Chinese biotechnology company, and Sooam Biotech, a South Korean company that specializes in animal cloning, will eventually churn out up to a million beef cattle embryos a year, as well as sniffer dogs, racehorses and other animals, its backers say. When completed, at a projected cost of $500 million, it will include a research laboratory, a gene bank and a museum.

Public education appeared to be a concern of Xu Xiaochun, Boyalife’s chief executive, during a conference call with journalists on Thursday, in which he sought to quell anxieties over the technology.

“Clone technology is already around us,” Mr. Xu said. “It’s just that not everyone knows about it.” He added that many strawberries and bananas sold in Chinese supermarkets were the products of this technology.
