The seven-nation summit meeting is scheduled to start in Tokyo Thursday morning. Here is a summary of the positions of France, West Germany, Great Britain and Japan, the four other major industrial nations, at the start of the talks.
Japan is busily preparing to be the proud host for this year's economic summit meeting but does not seem to expect it to produce any dramatic, immediate measures to solve the world's problems.
Its leaders are committed to the proposition that this summit must be a success just because it is held in their own capital, but so far they have not defined what results might be measured as successful.
They agree that energy must inevitably be the major issue for leaders of the seven nations. If Prime Minister Masayoshi Ohira will offer any new solutions to their problem of oil shortage, he is keeping that news close to his vest.
He agrees that new measures of conservation are necessary and seems eager for Japan to play a role in developing alternative energy sources. But his public statements have emphasized middle and long-range solutions, not immediate ones.
Japan imports almost all of its oil and would seem to be the world's most vulnerable country in an oilshort era. But it has not panicked over the current crisis as it did in 1973 and has introduced modest measures - closing gas stations on Sundays and holidays is the most severe - to cope with it.
A proposal generated in Europe to freeze oil imports at current levels for the next 10 years has been received cooly in Tokyo. Other countries with their own resources to fall back on in such an emergency might survive, officials say, but Japan would have a very though time.
There are some indications Japan might try to emerge as a peacemaker when the seven leaders sit down to talk in the lavishly appointed government guest house in central Tokyo. It does not want any strident confrontation with the OPEC countries and would act to cool off any hard-line approaches made by the Western powers.
It also may be placed in a position of mediating the currently growing feud over the Carter administration's controversial decision to grant a $5-a-barrel subsidy for imported heating fuel. Both Germany and France have objected strenuously to that subsidy. CAPTION: Map, no caption
