Suzuki shares, which have risen by about a fourth over the past year, inched down 0.4 percent to finish at 2,490 yen ($21) on Monday in Tokyo.
Suzuki will continue to hold its 11 percent stake in GM's South Korean subsidiary, GM Daewoo Auto and Technology Co. The GM-Suzuki joint venture production plant in Canada will also continue as will their cooperation in fuel-cell technology, Clarke said.
Suzuki has fared far better, expecting a 61 billion yen ($524 million) profit for the fiscal year ending March 31, as sales jumped 12 percent for the first nine months of the fiscal year from the same period a year ago.
