MUNICH : After the Fall . . .

Leaders of seven of the world’s leading industrial nations gather in the Bavarian capital beginning next Monday to deal with an array of problems stemming from the collapse of communism.

The so-called Group of Seven (the United States, Britain, Japan, Germany, Italy, France and Canada) are expected to approve a $24-billion aid package to rebuild post-Communist Russia, agree to fund at least the start of a multibillion-dollar program to build new safety measures into Soviet-era nuclear power stations still operating, and discuss ways of bringing stability to the region that was once Yugoslavia.

After they finish with their own business, the seven are to spend an afternoon with another global statesman--Russian President Boris N. Yeltsin, who is expected to make a personal plea for a five-year moratorium on repaying his country’s estimated $80 billion in external debts.
