US President Donald Trump, charging "Japan has been winning" on trade in recent decades, said he would push for more reciprocal trade with Washington's close US ally - but in a friendly way.Trump was speaking in Tokyo on the second day of a 12-day Asian trip expected to be dominated by North Korea and trade."The United States has suffered massive trade deficits at the hands of Japan for many, many years," Trump said at the start of a meeting with Japanese and US business leaders.Trump praised Japan for buying US military hardware, which he said was the "best military equipment in the world", but added that "many millions of cars are sold by Japan into the United States, whereas virtually no cars go from the United States into Japan"."We want free and reciprocal trade but right now our trade with Japan is not free and it's not reciprocal and I know it will be and we've started the process," Trump said. "I have no doubt that it will be done in a quick and very friendly manner."Trump also said Washington wants to make the United States the most attractive place to hire, invest and grow.
