President Mikhail Gorbachev told President Bush Saturday that his commitment to democratic reform at home and good relations with the United States are equally firm and he hopes for a summit meeting in Moscow, Tass reported.

Gorbachev told Bush by telephone that the two leaders' differences over a conventional armed forces treaty could be ironed out by a Soviet delegation leaving for the United States this week, allowing a summit to proceed in Moscow.No dates for the summit were mentioned in the Tass account, but both sides have constantly maintained they envision one in the first half of the year, which now would mean in June.

Both leaders expressed the hope, Tass said, that the topics at the summit "will be large-scale and will include such problems as power, engineering, housing, agriculture and ecology."

Gorbachev accepted Bush's offer to send a team of experts to the Soviet Union to analyze the food distribution system in the economically pressed nation, assistant press secretary Bill Harlow said in Washington.

The team, led by Undersecretary of Agriculture Richard T. Crowder, will leave Friday. Crowder will report to Bush as he weighs a Soviet request for $1.5 billion in grain credits.

Bush called Gorbachev from the presidential retreat at Camp David, Md., and the two spoke for 45 minutes, Harlow said.
