Olympic champions China are no doubt the world's top team and other countries are trying to match their style of play. That's the verdict of Dominican Republic team manager Cristobal Marte Hoffiz, who believes China are almost unbeatable at the moment and are certain to win the 3D-Gold FIVB World Grand Prix at Hong Kong Coliseum starting tomorrow. 'All the other countries like Cuba are trying to replicate what China are doing. China have raised the bar and are playing like the best team in the world. The progress they have made since winning gold in Athens is quite startling,' said Marte Hoffiz. 'We can notice that China are playing to new strengths and they are playing with a lot more pace. They are a very fast team. They are so fast now that it is almost impossible to block them.' China have undergone several notable changes since defeating Russia in last year's epic gold medal play-off match when they had to come back from two games down to win 3-2 in one of Athens' most poignant moments. They have retired several key players while recruiting a younger generation of stars. 'All the teams now are trying to follow this new system of play where speed is a factor. Before spiking and defence were the norm, but China are now playing with a lot more speed. 'It's a highly effective method of play and one that the other teams are trying to copy.' Marte Hoffiz was certain China would win the Hong Kong leg and easily qualify for next week's World Grand Prix finals in Japan. And the Dominican Republic will first get a taste of China's power when they are first up against the two-time Olympic champions tomorrow night. European powerhouse and former world champions Italy and Germany are also competing in the tournament that ends on Sunday. 'The Dominican Republic is a tiny country with an even smaller volleyball team. We are just a grain of rice compared to the giant rice paddy field of China. We cannot match China in all aspects of the game, but we will do our best,' said Marte Hoffiz. 'We have played China quite a number of times, beginning in a Montreal tournament in 2002, where we lost 3-0. 'We also played China in Ningbo recently and we managed to get a game off them. But they are still too powerful for us and I expect the Chinese to dominate us again.'
