From the article:
On September 20, Qintang District of Guigang City signed a cooperation framework agreement with Zhongji Mingyang New Energy Company to build an annual output of 300,000 vehicle high-speed and new energy vehicles with a total investment of about 1.5 billion yuan and a land area of ??about 500 mu. After all are completed and put into production, annual sales of about 15 billion yuan, annual tax of 500 million yuan.
The way I read this, it's an agreement between ZJMY and Qintang District to build a plant that will have potential output of $2.26 Billion. Qintang District is investing in the construction and providing some land for said construction. This does not read like a contract for the Qintang District to buy $2.26 Billion worth of EV's.
So not only is this NOT an agreement to purchase $2.26 Billion of EV's, it's describing a manufacturing facility that has not yet been built.
