This question is subject to debate since different people can see Clinton's policies in different ways. I would argue that the main characteristics of Clinton's foreign policy were A) a desire for more free trade and B) a desire to conduct humanitarian missions abroad even in places that were not of vital importance to the US.
One of the most famous things that Clinton did was to sign the NAFTA agreement with Canada and Mexico. This was a very controversial treaty that created a free trade zone encompassing all of North America. Clinton also helped persuade Congress to lower tariffs in general via the GATT agreement.
In addition, Clinton was eager to pursue humanitarian goals. This can be seen in his efforts to help stop the genocidal wars in the former Yugoslavia. He also pushed Congress to help Mexico economically when that country had a financial crisis in 1994.
Clinton's foreign policy, then, was characterized by a desire to pursue humanitarian goals and free trade.
