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.
The Tokyo summit will be Margaret Thatcher's second experience in summitry since she became Britain's Prime Minister early last month. The first was this month's European Economic Community summit in Strasbourg.
Several of Thatcher's top priorities in Tokyo will be the same as those in Strasbourg: establishing herself as a government leader of the first rank in such fast company, regaining some of Britain's lost influence in world affairs, and seeking energy policy decisions that benefit Britain both as a large oil consumer and an increasingly important oil producer.
She also will be campaigning for wide participation in the international conference on the Southeast Asian refugee problem that she has urged the United Nations to hold.
In less than two months as Prime Minister, Thatcher has emerged as a surprisingly outward-looking British leader. She already has had notably successful meetings with West German Chancellor Helmut Schmidt and French President Valery Giscard D'Estaing, and appears to have held her own in Strasbourg last week in presenting Britain's case for a better deal in the Common Market.
In economic discussion in Tokyo, Thatcher will be explaining her decision to begin switching the heavy burden of British taxes from income to consumption to spur growth in the long run, although it is expected to increase inflation and labor tension here first. The sharp rise in world oil prices also in fueling inflation.
In both the Common Market and the larger group of industrial democracies represented in Tokyo, Thatcher is expected to seek ways to use Britain's North Sea oil, while it lasts, as barter for financial and technological deals with richer nations that could benefit Britain after the oil is gone.
Thatcher has filled to top foreign relations posts in her Conservative Party government with experienced internationalists who will be looking for ways to increase Britain's overseas trade and influence. CAPTION: Map, no caption
