WORLD : U.S., Manila Link Aid, Bases

MANILA —  U.S. and Philippine negotiators agreed today to hold further talks on extending the lease for six American military bases after the United States promised it would try to increase aid.

Foreign Secretary Raul Manglapus, the chief Philippine negotiator, made the announcement at the end of five days of exploratory talks with U.S. negotiators on extending the lease for the bases beyond its Sept. 16, 1991, expiration.

Negotiators left unresolved two major differences: whether the United States failed to make full aid payments in return for use of the bases and when the facilities would actually have to close if the two sides cannot reach a lease agreement. No date was set for the next phase of the talks.
