The Regional Comprehensive Economic Partnership (RCEP) is not a "competitor" to the Trans-Pacific Partnership (or, as it's now known after adding the adjectives "comprehensive" and "progressive", the CPTPP).

Yes, the CPTPP very obviously excludes China while RCEP does not. But, unlike the former, the RCEP is a more traditional sort of trade deal, in which tariff cuts on tradeable goods - rather than high standards for labour, environmental and intellectual property protections - are at the centre of the discussion. That's part of the reason India is leery of signing it.
