Nikkei slips as investors sell blue chips, shippers

(Updates to midday)

TOKYO, June 13 (Reuters) - The Nikkei stock exchange gave up early gains to slide 0.2 percent on Friday as risk-shy investors worried about the results of a Group of Eight finance ministers' meeting this weekend sold blue chips such as Hitachi Ltd (6501.T).

Shippers extended losses as a key freight index plunged, while paper firms hit by the dollar's rise against the yen tumbled, weighing on the market.

The benchmark Nikkei .N225 gave up 22.31 points to 13,866.29, while the broader Topix slid 0.5 percent to 1,356.49. (Reporting by Elaine Lies)
