Is tendulkar the 1st to hit a double Ton???

In Gwalior Roop Singh Stadium the GOD of cricket Sachin was there on the pitch and he went on to score the double ton. Everyone including me is rating this knock as his best. However, is it true that Sachin is the first one to score a double ton in One day internationals.

If anyone is aware of women cricket teams then they can easily identify that the 1st double ton in one day international was hit way back in Women's World Cup 1997.
In extolling Sachin Tendulkar’s recent double hundred, many seem to have overlooked a fact. The little master isn’t the first to break the barrier in One Day Internationals (ODIs). It was Australian Belinda Clark, who notched up the first ODI double century in a World Cup match in 1997. The lady scored 29 more runs than Sachin off just eight more deliveries.

Agreed that what sachin has done, and the tower of records he is sitting on can shy down the cap any existing batsman, but being a cricketer if he himself does not know that he is not the first one to hit a double ton, so does he still remains the GOD of cricket............
