The Vietnamese government is facing a rise in public anger as its parliament debates a controversial bill to create three new special economic zones (SEZs), according to various news outlets.

The provision in the draft law allows foreign investors to lease the three SEZs for up to 99 years and has sparked fear of Chinese encroachment on Vietnamese soil.

The areas in Vietnam planned to be SEZs are Van Don in the northern Quang Ninh Province, Bac Van Phong in the central Khanh Hoa Province and Phu Quoc in the southern Kien Giang Province.

The bill does not explicitly mention any particular country but it is widely presumed China, Vietnam’s largest trading partner, would dominate investments in the SEZs.

Vietnam already has 18 SEZs.

The parliament is expected to vote on the SEZs draft law on June 15.
