MOSCOW (AP) _ President Boris Yeltsin has ended his vacation and is in ``normal'' health back at work at his country residence outside Moscow, his spokesman said today.

Spokesman Dmitry Yakushkin refused to say why Yeltsin abruptly canceled a dinner with visiting Japanese Prime Minister Keizo Obuchi on Thursday.

The two leaders had met that morning, Yeltsin's first high-level meeting since a respiratory virus infection sidelined him a month ago. He was shown on Russian television greeting the Japanese leader with a smile and handshake, appearing steadier than he has in public recently.

Yeltsin returned Sunday from a week at the Black Sea resort of Sochi to recover from what aides described as fatigue and high blood pressure.

The ailments, coming on top of the infection, have led to renewed speculations about his ability to govern.

The Kremlin initially would not say whether Yeltsin would resume his vacation after meeting Obuchi. But Yakushkin said today the vacation was over and that Yeltsin was working at his residence west of Moscow.

``The president's condition is normal,'' Yakushkin said without elaboration.

Yeltsin, 67, has suffered from various health troubles in the past, including a quintuple heart bypass surgery two years ago. He insists he has no crippling illness and intends to serve out his term, which runs until mid-2000.

He has canceled several foreign trips this fall because of health problems, and Russian media have quoted unidentified Kremlin aides as saying his ailments rule out any more visits abroad during the remainder of his term.

Yakushkin said Yeltsin would meet with German Chancellor Gerhard Schroeder in the Kremlin Tuesday and host a breakfast after their meeting.
