Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Trustees of
Pioneer Series Trust VII:

In planning and performing our audit of the financial statements of Pioneer
Global High Yield Fund and Pioneer Global Multisector Income Fund
(the "Funds") (two funds constituting Pioneer Series Trust VII) as of
and for the year ended October 31, 2019, in accordance with the standards
of the Public Company Accounting Oversight Board (United States), we
considered the Funds' internal control over financial reporting, including
controls over safeguarding securities, as a basis for designing our
auditing procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of Form N-CEN,
but not for the purpose of expressing an opinion on the effectiveness of
the Funds' internal control over financial reporting.  Accordingly, we
express no such opinion.

The management of the Funds is responsible for establishing and maintaining
effective internal control over financial reporting. In fulfilling this
responsibility, estimates and judgments by management are required to assess
the expected benefits and related costs of controls. A company's internal
control over financial reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with U.S.
generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (1) pertain
to the maintenance of records that, in reasonable detail, accurately and
fairly reflect the transactions and dispositions of the assets of the
company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with
U.S. generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of a company's assets that
could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that
the degree of compliance with the policies or procedures may deteriorate.

A deficiency in internal control over financial reporting exists when the
design or operation of a control does not allow management or employees,
in the normal course of performing their assigned functions, to
prevent or detect misstatements on a timely basis. A material weakness is a
deficiency, or a combination of deficiencies, in internal control over
financial reporting, such that there is a reasonable possibility that a
material misstatement of the company's annual or interim financial statements
will not be prevented or detected on a timely basis.

Our consideration of the Funds' internal control over financial reporting
was for the limited purpose described in the first paragraph and would not
necessarily disclose all deficiencies in internal control that might be
material weaknesses under standards established by the Public Company
Accounting Oversight Board (United States). However, we noted no deficiencies
in the Funds' internal control over financial reporting and its operation,
including controls over safeguarding securities that we consider to be a
material weakness as defined above as of October 31, 2019.

This report is intended solely for the information and use of management
and the Board of Trustees of Pioneer Series Trust VII, and the Securities
and Exchange Commission and is not intended to be and should not be used by
anyone other than these specified parties.
