A spokeswoman says Gov. Pat Quinn hopes to address some concerns about Illinois' business climate that Caterpillar Inc. cited in its decision not to build a new plant in the state.

Spokeswoman Brooke Anderson on Wednesday said Quinn plans to announce pension and Medicaid reforms later this month. She declined to provide details.

Peoria-based Caterpillar says it ruled Illinois out of plans to relocate a factory and 1,400 jobs from Japan over logistical problems and ongoing concerns about Illinois' business climate.

Caterpillar explained its decision in an email to Peoria County leaders. The county was 1 of fewer than a dozen Illinois locations trying to win the new plant.

In the email, the company says proximity to Caterpillar's division headquarters in Cary, N.C., was also a key factor.
