As GM courts partners, Toyota watches closely.

TOKYO - Toyota is keeping a close eye on the proposed alliance of General Motors, Nissan and Renault. The three-way tie-up doesn't appear to pose any immediate business threat to Japan's No. 1 car company, which continues to grow steadily in market share and profits while going it alone for the most part. Toyota Motor Corp. has opted for only limited collaboration with rivals, on certain products for certain markets.
