TAIPEI, June 22 (Reuters) - Taiwan Semiconductor Manufacturing Co (TSMC) has made up its order book with other customers now that it has lost China's Huawei Technologies Co Ltd, which is subject to U.S. sales restrictions, a government minister said on Monday. TSMC's clients include Huawei's chip division HiSilicon. However, the U.S. blacklisting of Huawei over security concerns and trade disputes with China has left the world's biggest contract chipmaker exposed to diplomatic developments between two countries where it also has production bases. Last month, the company unveiled plans for a $12-billion plant in the United States just hours before the U.S. Commerce Department outlined a proposal to amend chip export rules - a move that would restrict TSMC's sales to Huawei. The amendment would require licences for sales of semiconductors made abroad with U.S. technology to Huawei, the world's biggest supplier of telecoms equipment and its second-largest smartphone maker.
