To the Editor:

You quote President Clinton as saying that ''Russia and China, where the shackles of state socialism once choked off enterprise, are moving to join the thriving community of free democracies'' (news article, May 19). Both are moving to join the community of market economies, but only Russia has taken steps to become a free democracy.

Although flawed in many ways, Russia is an electoral democracy. China is an authoritarian regime. In Russia, leaders are elected, people can assemble, worship and travel freely, and the press can criticize the Government. In China, none of these freedoms exist.

Perhaps Mr. Clinton made a slip of the tongue. But for those who worry that he too often ignores violations of democratic rights in pursuit of market opportunities, this did not look so innocent.

U.S.-Russian relations offer one bright counter to the otherwise gloomy and complex set of issues facing American foreign policy makers after the September 11 terrorist attacks. Russian President Vladimir Putin was one of the first foreign leaders to speak directly to President Bush to express his condolences and offer his support for the American response. He followed these rhetorical pledges with concrete policies, including military and humanitarian support to the Northern Alliance in Afghanistan and Russian acquiescence to American troops in Central Asia.

Most Americans believe that President Clinton faces the most consequential moment of his career on Monday when he is scheduled to testify before Kenneth Starr's grand jury. In fact, a much bigger day for Clinton and the rest of the world comes just two weeks later when the president meets with Boris Yeltsin in Moscow. By this time, Russia very well may be in the throes of a major market meltdown, which in turn might trigger political upheaval on a scale similar to Indonesia. Different from Indonesia, however, Russia still has 10,000 nuclear weapons. The gravity of Russia's crisis makes this September summit one of the most important foreign policy missions of Clinton's presidency and an event of much greater importance than his grand jury testimony.

Between a continuation of engagement and a return to containment is a third path: realistic engagement. [Bush] needs to communicate to [Putin] that he believes in the possibility of Russia's integration into Europe and the Western community of states. But he also needs to clearly articulate the real terms of integration, terms that will require Russia to undergo serious political and economic changes. To help Russia integrate into the West, the American strategy must still be engagement, but with more realistic expectations about when, and with real standards for how this integration might occur.

President Bush thus must express his faith in Russia's ability to rejoin Europe as a democratic state with a market economy. Many within Russia do not believe the United States and the new administration in particular want to see Russia as part of the West. Bush should even be so bold as to present NATO membership for Russia as a real goal for the long term. Europe will only be whole and free, a goal Bush's father once articulated, if Russia is a member.

Most Russians still hope their country can become a full-fledged member of Europe. They do not want to become an autocratic ally of China seeking to confront the West. But a decade of disappointed expectations about democracy and markets, coupled with seemingly hostile acts from the West, has fueled doubts about Russia's place in the world. President Bush cannot eliminate this self-doubt overnight, but he can make clear American intentions toward Russia. By articulating a positive but realistic vision for Europe -- whole, free and including Russia -- he can help to reverse Russia's dangerous anti-Western drift.
