The Czech government approved on Wednesday a constitutional bill slightly modifying a section of the border with Austria due to anti-flood and water management measures. The legislation will mean the exchange of some land near the South Moravian towns of Břeclav and Lanžhot with neighbouring Austria. The Czech Republic and Austria agreed on the step on November 3 when the relevant treaty was signed. The government will submit it for ratification to the Czech Parliament. Under the treaty, the border will be now be delineated on the Dyje river. The 24-hectare area is administered by Břeclav and Lanžhot. The acreage to be swapped is the same in Austria and the Czech Republic.
