He improved his times at the 2012 FINA Swimming World Cup, where he competed at all stops of the World Cup circuit and achieved a fourth-place finish across all stops. He concluded the year's short course season at the 2012 World Short Course Championships. Here Seto won the first international medals of his career.

He then competed in the 200-metre individual medley, where he was able to sprint past Cseh for the silver medal in a time of 1:52.80.

Seto was still coming into the 2013 World Aquatics Championships in Barcelona, Spain, relatively unknown. He swam both individual medley events. In the 200-metre, his first event, he swam a personal best in the semifinals with a time of 1:58.03, and then finished a touch slower in the final the next night to finish seventh overall. In his best event of the Championships, the 400-metre individual medley, Seto qualified first for the final and then won his first long course world title by finishing first in a time of 4:08.69, about half a second ahead of second-place finisher Chase Kalisz of the United States.
