President Boris Yeltsin returned to his Kremlin office Friday after a week spent at home nursing a respiratory infection.

The president previously had canceled all his events this week on the advice of his doctors and had been expected to remain at his suburban residence, Gorky-9.But early Friday, Yeltsin showed up at the Kremlin, where he spent several hours working on plans for a summit in Russia next week with German Chancellor Helmut Kohl and French President Jacques Chirac.

Russian television showed brief footage of Yeltsin walking to meet his aides and then facing them across the table. Yeltsin looked at ease as he conversed, smiling frequently.

Yeltsin also had telephone conversations with Prime Minister Vik-tor Chernomyrdin and Foreign Minister Yevgeny Primakov.

Yeltsin, 67, has a reputation as a restless patient, often ignoring the advice of his doctors and quickly resuming a busy schedule following bouts of illness.

The president has been sick several times in recent years and underwent heart bypass surgery in 1996.

Next week's summit will touch on European issues as well as a program for cooperation in the economic, social and humanitarian fields, said Yeltsin's spokesman, Sergei Yastrzhembsky, who met with Yeltsin.

Among other events on Yeltsin's schedule is a March 30 meeting in Moscow with U.N. Secretary-General Kofi Annan.
