The government is worried about the recent decline of Tokyo stock prices but has no plans to intervene at the moment, Chief Cabinet Secretary Yasuo Fukuda said Thursday.

"We are slightly concerned about the fall," the top government spokesman said at a news conference. "But we are carefully following the situation and are not thinking about doing anything at the moment.

"When we view the nation's economy as a whole, we basically believe there are no special problems that should be pointed out."

The Nikkei Stock Average plunged to a 27-month closing low Thursday as bearishness proved too strong for Tokyo to lift itself on overnight Wall Street gains.

The benchmark 225-issue Nikkei slid 231.58 points, or 1.72 percent, to 13,201.07, its lowest close since Oct. 15, 1998.
