LONDON (AP) – A month before the IOC vote, the South Korean city of Pyeongchang received the best overall review Monday in a report assessing the three bids for the 2014 Winter Olympics.

Pyeongchang, which finished second to Vancouver in the race for the 2010 Games, got the most favorable ratings in a technical report by the International Olympic Committee’s evaluation commission.

Sochi, Russia, and Salzburg, Austria, are the other candidates.

The report could play an important role in swaying undecided members when the full IOC general assembly selects the 2014 host city by secret ballot on July 4 in Guatemala City.

The 76-page report, based on visits to the three bid cities this winter by a panel of experts, assessed the candidates on a number of key issues, including sports venues, security, financing, accommodation, transportation and government and public support.

While the IOC did not rank the cities, the report identified strengths and weaknesses which could be used to differentiate them in overall terms.

The report listed no significant weaknesses in the bid from Pyeongchang, which focuses on expanding winter sports in Asia and fostering peace on the Korean peninsula.

The IOC warned, however, that Sochi’s major infrastructure plans would need to be “tightly monitored,” and cited Salzburg for lacking detail in its bid documents, offering some hotel rooms below IOC standards and underestimating security costs.
