0723 GMT - The polarization of trade and artificial-intelligence development between China and the U.S. is likely to continue for the foreseeable future, says Eastspring Investments in a note. The meeting between President Trump and Chinese leader Xi Jinping "delivered much pageantry, but essentially no tangible economic results," says Eastspring. The continuing divergence between the two economic powers suggests investment in China has to be centered on earnings streams supported by government policy and specific areas of local demand, Eastspring adds. Meanwhile, elevated oil prices stemming from the U.S.-Iran conflict and a potential ban on U.S. diesel exports could push diesel prices in certain parts of Asia higher, bleeding into inflation and likely pressuring regional currencies including the Korean won, Indian rupee and Thai baht, the asset manager says.
