BOSNIAN SERBS REJECT PEACE PLAN Bosnian Serbs deepened their self-imposed isolation, voting overwhelmingly against a peace plan endorsed by friends and enemies alike, according to initial results yesterday. Concerns grew that the 28-month-long Bosnian war would turn even more violent with the defiant rejection. As Bosnian Serbs finished their weekend referendum Sunday, their troops battled soldiers of Bosnia's Muslim-led government north of Sarajevo in some of the fiercest fighting in recent weeks. Referendum officials said more than 90 percent of Bosnian Serbs who voted rejected the peace plan that was put forward by the United States, Russia, France, Britain, and Germany. There were reports of voting irregularities. But there was no question the majority of participants, subjected to extensive antiplan propaganda by the Bosnian Serb leadership, rejected the plan. US-Japanese trade

Japan is doing its part to achieve a trade agreement with the United States and expects more cooperation from Washington, Japanese Prime Minister Tomiichi Murayama said yesterday. His comments were made in Singapore, the final stop on a four-nation tour of Southeast Asia, and raise the likelihood of a US-Japan clash over trade as Washington's Sept. 30 deadline for an agreement nears. Caribbean gathering

Caribbean foreign ministers arrived Sunday in Kingston, Jamaica, for a meeting with officials from the United States, Canada, the United Nations, and the Organization of American States to examine plans for a possible invasion of Haiti. The talks involving officials of the 13-member Caribbean Community were to begin yesterday. The delegates will discuss ways of implementing UN Resolution 940, which authorizes the use of military force to restore ousted Haitian President Jean-Bertrande Aristide. Most expensive airport

Kansai International Airport, which opened yesterday in Osaka, Japan, is the world's most expensive. Built on a man-made island in Osaka Bay, it charges planes $24 a ton to land, the steepest landing fee anywhere. It also cost more than any other airport - $15 billion for design and construction. By comparison, Denver's controversial new airport cost about $3.7 billion to design and build. Westinghouse strike averted

Westinghouse Electric Corporation and three unions representing about 5,400 workers reached a tentative contract agreement hours after a vote to strike early yesterday. The four-year agreement, which the rank and file was expected to vote on within two weeks, includes a wage increase of 13 percent over the life of the contract and offers a majority of workers a managed health-care plan, the company said. Health benefits had been a major stumbling block in the negotiations, a union spokesman said.
