​PCP brought a Resolution Project to Parliament for the rejection of the Free Commerce and Services ​agreements, namely the Comprehensive Economic and Trade Agreement (CETA) between the European Union and Canada.

In this project, PCP denounces that CETA, if it is ratified, will harbor negative consequences for States such as Portugal, namely deprotection, deregulation and destruction of its productive capacity, together with a significant attack upon worker's rights.

​ It also states that CETA is an instrument to ​reduce social, labor, environmental and public health rights, to place the interests of the multinationals above the rights and interests of peoples and the constitutions and sovereignty of States, representing a further step in the escalation of liberalization of global commerce – with grave consequences for Portugal.

PCP also denounced that these negotiations are marked by a profound democratic deficit and by pressures and blackmails upon the peoples who in the European Union have raised their voice against this agreement, as well as the attempt to ratify part of the accord without subjecting it to the scrutiny of national parliaments.

​ Fighting for mutually advantageous cooperation agreements, that ensure national sovereignty, that answer the needs and interests of the peoples, that defend and promote social, labor and democratic rights, the right to economic and social development, PCP raised the demand that the Portuguese government:

- Reject ​the objectives and aims of CETA and, consequently, this agreement;

- Defend in the European Union, the national economy and production, the rights of the Portuguese people and national sovereignty.

​ - Demonstrate in the institutions of the ​European Union, the position that CETA, as well as other free commerce and services agreements in negotiation by the EU, should be obligatorily subject to the process of ratification by member-states.
