TOKYO (AP) -- International Olympic Committee Vice President John Coates praised preparations for the 2020 Tokyo Olympics on Wednesday while trying to calm concerns over the rising cost of the new National Stadium.
The Tokyo municipal government has been arguing with the central government over how costs of the new stadium will be shared.
The Japanese government said on Monday it expects the overall costs will soar to $2 billion, almost double the original estimate of $1.3 billion.
Calling National Stadium a national project, Coates said its use goes well beyond the 2019 Rugby World Cup then the Olympics.
Coates also pointed out that under Tokyo's revised venue plan, use of existing venues has risen from 33 percent to 50 percent for a saving $1.7 billion.
