``We intend to stick to our nuclear policy in the security interests of our country and any attempts to pressurise it to take a particular line would not work,'' President K R Narayanan told his German counterpart Roman Herzog and Chancellor Helmut Kohl.

At the same time, he emphasised that there was no dilution in India's commitment to a world free of weapons of mass destruction. Official sources told reporters after Narayanan's talks with the German leaders that there was a ``good and positive response'' from Germany to India's stand on security and disarmament issues.

New Delhi and Bonn signed an agreement on cooperation in the environment sector on the sidelines of the first-ever state visit by an Indian president here since the 1990 German unification.

Narayanan, who was accorded a ceremonial welcomewith full military honours at the Presidential Palace Villa Hammerschmidt, shared with the German leaders the determination of the two nations to stamp out terrorism.
