Gov. Christie flew to Illinois on Friday, trying to sway corporate leaders to bring their business east.
His administration did not release details of the meetings, "in the interest of discretion," said Michael Drewniak, a spokesman for the governor.
Christie, along with governors in Indiana and Wisconsin, has been trying to pry jobs from Illinois after Democratic Gov. Pat Quinn signed a record 67 percent tax increase Jan. 12.
Illinois raised its flat personal income tax rate to 5 percent from 3 percent, but that is below New Jersey's graduated rates for taxable incomes above $40,000, Quinn's press secretary, Brie Callahan, said in an interview last week. And while the Illinois corporate rate is increasing to 7 percent from 4.8 percent, that is still below New Jersey's 9 percent rate, she said.
