"A car has 20,000 to 30,000 parts, and production will not be complete if even one part is missing," he said.
The government should focus on the flood situation before talking about rehabilitation plans for businesses, says Toyota Motor Thailand (TMT).
"We want the government to solve the flooding first so we can assess the damage. This is affecting not only Thailand, but also [company operations in] Japan and the rest of the world too. Rehabilitation plans can come later," said President Kyoichi Tanada after a crisis meeting with industry permanent secretary Witoon Simachokdee.
The Industrial Estate Association earlier proposed that the government rehabilitate flood-hit industrial estates within 45 days, although Mr Tanada said that time line would differ for individual factories.
