TOKYO — Nissan and Renault met on Wednesday to discuss the future of their carmaking alliance after a surprise announcement by the French automaker that it was considering a merger with Fiat Chrysler.

The merger proposal surprised the industry in general and Nissan in particular; it was not part of the talks and was informed about the negotiations between its partner and Fiat Chrysler shortly before the announcement on Monday.

The meeting on Wednesday for members of the Renault Nissan Alliance, which also includes Mitsubishi, took place at Nissan’s headquarters in Yokohama and ended shortly before noon. The group issued a brief statement that the carmakers had carried out “an open and transparent discussion” on the merger proposal as well as other matters.

Nissan has tried to put a good face on the situation. Heading into the meeting on Wednesday morning, Nissan’s chief executive, Hiroto Saikawa, said that he was examining how the deal would affect his company, the economic daily Nikkei reported.
