A million Shenzhen residents have signed petitions opposing the extension of Hong Kong landfills near the border.
Shenzhen National People's Congress deputy Yang Qin said several NPC deputies in the city are planning to visit Hong Kong to hand over the signatures to the Legislative Council.
The government last week withdrew a request for funding to conduct an environmental impact assessment of the landfills.
Since the end of last month, the Shenzhen Volunteer Union with the support of five NPC deputies set up booths to collect signatures.
Yang said most of those signing come from Lotus Hill Park and Shenzhen Book City close to the border.
He said he will submit a proposal on the landfills to the annual plenary sessions of Shenzhen's legislature and political advisory body.
The proposal calls for the Hong Kong government to listen to the voices and the opinions of Shenzhen people and to cooperate on pollution issues.
He said some Hong Kong lawmakers will be invited to Shenzhen to discuss the landfill expansions with NPC deputies.
In Shenzhen's Shekou, residents have been complaining of the odor from the Tuen Mun landfill, located 16 kilometers away.
