JEFFERSON CITY, Mo. (AP) — Missouri senators have given initial approval to legislation seeking a potential truce in an economic competition with bordering Kansas.

Under legislation endorsed Wednesday, Missouri would stop offering incentives aimed at getting businesses to come from several Kansas counties. The moratorium would take effect if Kansas enacts a similar moratorium through legislation or executive order.

The proposal would apply to Jackson, Clay, Platte and Cass counties in Missouri, and to Wyandotte, Johnson, Douglas and Miami counties in Kansas. The states have waived hundreds of millions of dollars in tax revenues competing with each other for businesses around Kansas City.

Missouri’s legislation requires another vote before it moves to the state House.
