''The crude market has reacted negatively to comments from the Chinese government that it will tolerate a slower rate of economic growth, '' Victor Shum, managing director at IHS Purvin and Gertz in Singapore, told.

''The comments by Xi further deepened concerns about the Chinese economy after the poor manufacturing data last week, '' Shum added.
