Chinese lawmakers are looking at limiting foreign access to the country's seed production industry.

The Standing Committee of the National People's Congress is now considering an amendment to make seed production part of the national security lexicon.

If passed, this would require seed producers or research firms with any foreign investment undergo new security assessments.

Foreign investment, mergers or technological cooperation by foreign companies with Chinese seed producers will also be strictly scrutinized.

The proposed changes come amid concerns in China about the production of genetically-modified foods.
