Traders in the Rotterdam spot market said the news was unlikely to have much impact on the market. The propsed new Soviet price is still some 40c below current spot quotes. The traders said most Soviet customers were likely to accept the new price, although Finland might query it within the framework of its general trade relations with the USSR.  CITYNEWS HEADLINES 120 
