XIAN - China's Sinopec and Kazakh state-owned oil and gas company KazMunayGaz have agreed key terms for a potential investment in a polyethylene plant in Kazakhstan's western Atyrau region, according to a statement by Sinopec on Thursday.

The agreement was signed on the sidelines of the ongoing China-Central Asia Summit in Xian, where China's president Xi Jinping met with Kazakh president Kassym-Jomart Tokayev on Wednesday. A final decision on the proposed investment will be made in 2024, the Sinopec statement said.
