GLP formed a committee of independent directors and said it had taken measures to alleviate potential conflicts of interest. It said on Friday that it chose the Chinese consortium because it had more deal certainty and "limited conditionality", reducing the "execution risk".
"After an extensive evaluation of all final proposals received, the Special Committee decided on the proposed scheme, which we believe is compelling and value-enhancing for all shareholders," Seek Ngee Huat, chairman of GLP's board, said in a joint statement with the winning consortium.
The acquisition is not conditional on getting antitrust approvals or a green light from the Committee on Foreign Investment in the United States (CFIUS), among others.
Singapore wealth fund GIC, which owns 37 percent of GLP, said it supports the transaction.
Last year, GIC nudged GLP to start a strategic review of its business. GLP then hired JPMorgan as its financial adviser and Allen & Gledhill as its legal adviser.
GLP's shares have since soared nearly 50 percent to their highest levels in more than three years.
The Chinese group is offering S$3.38 in cash per share, representing 81 percent premium over its 12-month volume weighted average price and a 25 percent premium over its last full trading day before the announcement.
The proposed acquisition will be done by way of a scheme of arrangement and the Chinese group plans to delist and take the Singapore-listed firm private.
Citigroup, Goldman Sachs and Morgan Stanley acted as lead joint financial advisers for the consortium and are providing the financial resources confirmation related to the purchase. DBS Bank and China International Capital Corporation also advised the consortium.
