Tokyo stocks sank deeper Wednesday on rekindled anxiety about a prolonged U.S.-China trade war. The 225-issue Nikkei average dived 244.58 points, or 1.05 percent, to end at 23,135.23, after falling 149.69 points Tuesday. The Topix index of all TSE first section issues finished down 3.46 points, or 0.20 percent, at 1,703.27, following a 7.76-point drop the previous day. The Tokyo market went south from the outset after U.S. President Donald Trump told reporters Tuesday that he thinks it better to wait until the 2020 presidential election to conclude a preliminary trade deal with China. Although stocks showed some resilience later in the morning, the yen's appreciation against the dollar also helped kept the Nikkei and Topix indexes in negative territory throughout the Wednesday session, brokers said.
